Calculate SLD for SDTM.TR domain — derive

Usage

derive_sld(
  sdtm_obj,
  testcd = "DIAMETER",
  group = c("TRMETHOD", "TRGRPID"),
  observation_filter = "TRGRPID == 'TARGET'"
)

Arguments

sdtm_obj: A SDTM object.
testcd: The TRTESTCD to select for SLD calculation, as character.
group: Grouping variables, as character.
observation_filter: A filter term, as character.

Value

A SDTM object.

Details

Calculate the sum of longest diameters (SLD) and number of lesions by subject and time point, and add as rows. If a SDTM.TR domain is not included in the input SDTM object, the SDTM object is returned as-is.
