When extracting data from OpenClinica 220.127.116.11, I get the database values of the selected items from radio buttons etc. E.g. I get a "1" when the "Yes" from a "Yes, No" / "1, 0" reponse options text / response values set has been selected.
In this example, the value "1" is rather obvious, but it may not be so in all cases: "No, absolutely not", "Nah, not really", "Well ...", "Perhaps a bit", "Sure thing!" coded as "NAN, NNR, W, PB, ST" isn't that obvious. The CRF itself - when viewed in OpenClinica - doesn't necessarily provide enough information to shed light on the mystic "NAN" and "W" values in the data set, as these may not at all correspond with the textual representation of the CRF.
I have found a place where these option / value sets are visible, deep down in the Build Study, but this isn't available when you're a data specialist or an investigator, so how is the data specialist informed about these option / value sets? I cannot find an option to add this of the data set when extracting data?
