Cox hazard ratio with the investigational arm in the numerator

Description

The reference level is the other arm, so a ratio below 1 favours the investigational arm. One row is returned, for binding into a forest.

Usage

cox_hr(data, time, event, arm, investigational = "Investigational",
  subgroup = "Overall")

Arguments

data	Subject-level data.
time, event, arm	Column names.
investigational	Level of arm treated as the experimental arm.
subgroup	Label stored in the result.

Value

A one-row data frame with subgroup, estimate, limits and n.

Examples

onc <- simulate_oncology(n_per_arm = 20)
cox_hr(onc$adsl, "os_months", "os_event", "arm")
