如何在較早的時間點停止KaplanMeier曲線？-有解無憂

我有以下資料，我正在使用此代碼繪制 Kaplan Meier 曲線：

fit <- survfit(Surv(time_to_first_g3_tox, grade_3_tox_bool) ~ tx_start_schedule, data = df)
ggsurvplot(fit, risk.table = TRUE, surv.median.line = "hv")

這一直持續到 1200 天，但我希望情節和表格在 90 天時停止。這可能嗎？謝謝

下面的資料框：

uj5u.com熱心網友回復：

您可以使用xlimwithbreak.x.by來控制中斷，如下所示：

library(survival)
library(survminer)

fit <- survfit(Surv(time_to_first_g3_tox, grade_3_tox_bool) ~ tx_start_schedule, data = df)
ggsurvplot(fit, risk.table = TRUE, surv.median.line = "hv", break.x.by = c(10), xlim = c(0, 90))
#> Warning in .add_surv_median(p, fit, type = surv.median.line, fun = fun, : Median
#> survival not reached.
