create_extrafields {psm3mkv}

Create the additional time-to-event endpoints, adjusting for cutpoint

Description

Create the additional time-to-event endpoints, adjusting for cutpoint

Usage

create_extrafields(ds, cuttime = 0)

Arguments

ds

Patient-level dataset

cuttime

Time cutpoint

Value

Tibble of complete patient-level dataset, adjusted for cutpoint ttp.durn, pfs.durn, ppd.durn and os.durn are the durations of TTP (time to progression), PFS (progression-free survival), PPD (pre-progression death) and OS (overall survival) respectively beyond the cutpoint. pps.durn is the duration of survival beyond progression, irrespective of the cutpoint. pps.odurn is the difference between ttp.durn and os.durn (which may be different to pps.durn). ttp.flag, pfs.flag, ppd.flag, os.flag, and pps.flag are event flag indicators for TTP, PFS, PPD, OS and PPS respectively (1=event, 0=censoring).

Examples

bosonc <- create_dummydata("flexbosms")
create_extrafields(bosonc, cuttime=10)
