f.sponsorType {ctrdata} | R Documentation |
Calculate type of sponsor of a study
Description
Trial concept calculated: type or class of the sponsor(s) of the study. No specific field is available in ISRCTN; thus, sponsor type is set to 'other'. Note: If several sponsors, sponsor type is deemed 'mixed' if there is both, a commercial and a non-commercial sponsor(s).
Usage
f.sponsorType(df = NULL)
Arguments
df |
data frame such as from dbGetFieldsIntoDf. If 'NULL', prints fields needed in 'df' for calculating this trial concept, which can be used with dbGetFieldsIntoDf. |
Value
data frame with columns '_id' and '.sponsorType', which is a factor with levels 'for profit', 'not for profit', 'mixed' (not and for profit sponsors) or 'other'.
Examples
# fields needed
f.sponsorType()
# apply trial concept when creating data frame
