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, ... )
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. |
