Calculate type of control data collected in a study

Description

Trial concept calculated: type or class of the lead or main sponsor of the trial. Some information is not yet mapped (e.g., "NETWORK" in CTGOV2). No specific field is available in ISRCTN.

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' or 'Other'.

Examples

# fields needed
f.sponsorType()

## Not run: 

# apply trial concept when creating data frame
dbc <- nodbi::src_sqlite(
  dbname = system.file("extdata", "demo.sqlite", package = "ctrdata"),
  collection = "my_trials", flags = RSQLite::SQLITE_RO)
trialsDf <- dbGetFieldsIntoDf(
  calculate = "f.sponsorType",
  con = dbc)
