Add Survival Curves of Pooled Patients onto the Main Plot

Add survival curves of pooled patients onto the main plot stratified by grouping variables.

ggsurvplot_add_all(
  fit,
  data,
  legend.title = "Strata",
  legend.labs = NULL,
  pval = FALSE,
  ...
)

Arguments

fit

an object of class survfit.

data

a dataset used to fit survival curves. If not supplied then data will be extracted from 'fit' object.

legend.title

legend title.

legend.labs

character vector specifying legend labels. Used to replace the names of the strata from the fit. Should be given in the same order as those strata.

pval

logical value, a numeric or a string. If logical and TRUE, the p-value is added on the plot. If numeric, than the computet p-value is substituted with the one passed with this parameter. If character, then the customized string appears on the plot. See examples - Example 3.

...

other arguments passed to the ggsurvplot() function.

Value

Return a ggsurvplot.
