CVB DATA GUIDEHOW TO SUBMIT DATAThis document describes how to submit data for studies reported to CVB.1 Overview – How to submit data Organize the data set according to a data format. Save the data set in Comma Separated Value (CSV) files. Use this data set in your own data analysis. Submit the CSV files to CVB.2 Data Formats2.1 What is a data format?A data format is a defined way of arraying data. A data format definition specifies one or more relatedtables that have a particular structure.2.2 What does a data format do?Data formats provide a common “language” for sharing data sets. The CVB data formats are designed forseveral characteristics. One of the most important is to facilitate machine reading and processing.2.3 Data Format definitions are found in the Appendix3 CSV FilesA CSV file is a type of text file. Use CSV files, not another electronic file type. (If you think an exception is warranted, please check first.) Each table in a data format should be in a separate CSV file. Files should be named according the naming convention of its data format. See Appendix Section 3.2: Creating CSV Files for CVB Statistics for more information.4 Before submission4.1 Prepare the data set Select the appropriate Data FormatTake into account Data PrinciplesPerform quality checks for internal consistency4.2 Use the data setFirst prepare the data set, then use the data set in your analysis (if you choose to do a statistical analysis).By working with the data set before submitting it to CVB, your analysis serves as a final check of thevalidity and quality of the data set before submission. Don’t leave the preparation of the data set forsubmission to the end. Your programming code should usually show how you read in the data from the CSV files.CVBDataGuidePage 1 of 3820 May 2019

1 Data Formats1.1 IntroductionA data format is a defined way of arraying data. A data format definition specifies one or more related tables thathave a particular structure. The table specifications include “mandatory columns” – those that are alwaysnecessary, and “other columns” – those that may be necessary for specific studies. Both have required namingconventions.The data formats are designed for the types of studies commonly submitted to CVB. To help choose a suitabledata format, below is a list of study types with a suggested data format that often works. However if you thinkthat your data doesn’t quite fit, feel free to Build Your Own Format or contact CVB statistics for advice.POSSIBLE DATA FORMATS FOR SOME COMMON STUDY TYPESCategoryStudy TypeData y or other efficacy surrogateClinicalNatural exposure field efficacyClinicalField SafetyFST by VSM 800.204FST in target speciesGeneral Field SafetyFST in target species – poultry or fishPoultry/Fish Field SafetyClinical SafetyDesigned safety studyClinicalAssaye.g. Assay validationReagent changeManufacturing processInactivation kineticsStabilityRelative potency ELISAELISACheckerboard ELISA optimizationCheckerboardTitrationMulti-well AssayCountMulti-well AssayConventional PCRMulti-well AssayOther dilution assays (e.g. RID, dot blot, etc.)Multi-well AssayDichotomous response (pos/neg)DichotomousDichotomous response (e.g. single use device)Diagnostic Kit-DichotomousQuantitative response (e.g. OD, Ct)Diagnostic Kit-QuantitativeSerological equivalenceClinicalDiagnostic Test KitOtherCVBDataGuide – AppendixPage 4 of 3820 May 2019

1.2 ELISA Format1.2.1Introduction1.2.2What to Submit1.2.3TablesThis format is for enzyme-linked immunosorbent assays (ELISA) used to estimate relative potency oranalyte concentration. This assay is performed in a 96-well microtiter plate. For assays that are performedon a 96-well microtiter plate, but is not an RP ELISA, please see the Multi-well Assay Format.When submitting electronic data that correspond to relative potency ELISA data format, include a total offour (4) CSV files, one corresponding to each of the 4 tables labeled below.This format includes four tables, named plateinfo, od, layout, and dilution. Except for plateinfo, thetables are laid out as stacked 8 12 arrays of plate information, with one additional column. The datashould be presented exactly as arrayed on the plate. In other words, the rows are A-H and the columns are1-12.TableDescriptionplateinfoInformation about each individual plate.odThe optical density readings of the wells. Every well shouldhave a numeric result.The contents of each well, usually the preparation identifier.Include information on every -12plateIDOther Columnstechniciancapture antibodyantigenroleetc.nonenoneFor columns 1-12, if no material was added to the well, use“NA”. Note that the word “blank” should not be used for anempty well, since it usually refers to the preparation known asthe reagent blank. For wells that are not part of the study, pleaseuse “NPS”.dilutionThe dilution of the material in each well.For columns 1-12, specify “undiluted” wells as 1. Use number(8, 0.125, NA) not text (1:8, 1/8, NPS). Do not use commas(1,024) that might cause a number to be interpreted as text. Forten-fold dilutions, scientific notation (1e9) may be used to avoiddata entry errors of large dilutions ) Relationships between serial number, product codenumber and test data results.plateIDserial IDproduct codetest outcomerelative potencyetc.1.2.4Submission subtypes with additional required informationAssay validation: Please provide the Relative Potency (RP), product code (prod code), and plate role(plate role). The RP and product codes can be added as columns to the serialtesting table. The plate role,which would identify the aspect of the assay validation the plate was used in, should be added as acolumn to the plateinfo table (add multiple columns if a plate has more than one role).CVBDataGuide – ELISAPage 5 of 3820 May 2019

Stability – product: Please add a column for the Relative Potency (RP) results, serial fill date (fill date),and bulk date (bulk date) for each serial to the serialtesting table. If testing is conducted on bulk and finalcontainer, please add the column MaterialTested.Stability - reference: Please provide the product code (prod code) for each serial by adding a column tothe serialtesting table.Note: When submitting the Relative Potency (RP) results which rely on a linear model fit, please alsoprovide the start and end dilutions 1 used for each serial and reference that the linear model was fit to.Please see the serialtesting table example below for prefered column names.1.2.5ExampleBelow are examples of the 4 tables in the format that should be included when submitting a study to theCVB. The fifth table, serialtesting, is used when specific serial information needs to be included.Integer where 1 is the first dilution in the series, 2 is the second, etc. Not the same as dil, and not the column number. In example1.2.5, the linear model is fit to the 1st – 4th dilutions for the reference (dil 1:1 – 1:8) and the linear model is fit to the 2nd to 5th dilutionsfor the serial (dil 1:2 – 1:16).1CVBDataGuide – ELISAPage 6 of 3820 May 2019

1.3 Clinical Format1.3.1Introduction1.3.2What to Submit1.3.3TablesThis format is intended for designed experiments with live animals. This includes vaccination-challengeefficacy studies, natural exposure or field efficacy studies, other experimental efficacy studies without achallenge, feasibility studies involving target species or laboratory surrogates, and serological studies. It isnot intended for simple in vivo titrations involving lab animals, for those studies see DichotomousFormat.When submitting electronic data in the Clinical Format, include a total of three (3) CSV files, onecorresponding to each of the 3 tables listed below. If no daily observations are taken, a repeated table maynot be necessary.TableDescriptionindividualThis table will contain all the information for the individualanimal. Include any information that pertains to housing orlitter (if applicable). It may also include any observations thatare made once, usually at necropsy.repeatedThis table will contain information on outcomes that wereobserved more than once. In most cases this means the dailyobservations. It should have an animal ID (identical to theone used in the individual table), a day column, and otherobservation columns.This table is for the explanation of all the columns names inthe previous two tables. You will provide the column nameexactly as it appears in the previous two tables, a briefdescription of the column, and what table the column belongsto.variablesCVBDataGuide – Clinical Format8 of tabledescriptionOther Columnssexdate of birthlitterpenlung lesionslymphoid ts20 May 2019

Each comma in a sentence is to be tagged as T[rue] (it is a comma splice) or F[alse] (it is not). Consider the sentence “Then, he chased after eled as FTF, since only the second comma consti-tutes a comma splice (the relative pronoun “which” should fol

Comma Splices Comma splices are similar to run-on sentences because they also incorrectly connect two simple sentences. A comma splice occurs when two simple sentences are connected with only a comma. Comma Splice example: My family bakes together nearly every night, we then get to enjoy everything we make together.

Comma Splice A comma splice is a form of run-on sentence. The Bedford Handbook states that the comma splice is "a far more common type of run-on sentence" (235). These often occur when the author inserts appropriate punctuation marks, but then fails to include the appropriate conjunction word. Examples of a Comma Spice:
