Trial concept calculated: Calculates if results have been recorded in the register, as structured data, reports or publications, for example. Requires loading results-related information for EUCTR.

Usage

f.hasResults(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 new column `.hasResults` (logical).

Examples

# fields needed
f.hasResults()
#> $euctr
#> [1] "endPoints.endPoint"

#> $ctgov
