  surv_diff = c("rate_diff", "rate_diff_ci", "ztest_pval")
)

.stats <- c("pt_at_risk", "rate_diff")
h_split_param(.stats, .stats, f = f)

# $surv
# [1] "pt_at_risk"
#
# $surv_diff
# [1] "rate_diff"

.formats <- c("pt_at_risk" = "xx", "event_free_rate" = "xxx")
h_split_param(.formats, names(.formats), f = f)

# $surv
# pt_at_risk event_free_rate
# "xx"           "xxx"
