d_survival_subgroups_colvars {tern}

Labels for column variables in survival duration by subgroup table

Description

Internal function to check variables included in tabulate_survival_subgroups() and create column labels.

Usage

• n_tot: Total number of observations per group.

• n: Number of observations per group.

• median: Median survival time.

• hr: Hazard ratio.

• ci: Confidence interval of hazard ratio.

• pval: p-value of the effect. Note, one of the statistics n_tot and n_tot_events, as well as both hr and ci are required.

conf_level

(proportion)
confidence level of the interval.

method

(string)
p-value method for testing hazard ratio = 1.

time_unit

(string)
label with unit of median survival time. Default NULL skips displaying unit.
