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 `for profit` if any sponsor is commercial.
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` or `other`.
