Helper Function: Survival Estimation Grob

Usage

h_grob_median_surv(
  fit_km,
  armval = "All",
  x = 0.9,
  y = 0.9,
  width = grid::unit(0.3, "npc"),
  ttheme = gridExtra::ttheme_default()
)

Arguments

fit_km

(survfit)
result of survival::survfit().

armval

(string)
used as strata name when treatment arm variable only has one level. Default is "All".

x

(numeric)
a value between 0 and 1 specifying x-location.

y

(numeric)
a value between 0 and 1 specifying y-location.

width

(unit)
width (as a unit) to use when printing the grob.

ttheme

(list)
see gridExtra::ttheme_default().

Value

A grob of a table containing statistics N, Median, and XX% CI (XX taken from fit_km).
