如何在 lifelines Kaplan-Meier 图中隐藏置信区间
使用 lifelines 库，你可以轻松绘制 Kaplan-Meier 图，例如在我们之前的文章最小 Python Kaplan-Meier 图示例中所见：
kaplan_meier_example.py
from lifelines.datasets import load_leukemia
from lifelines import KaplanMeierFitter
df = load_leukemia()
kmf = KaplanMeierFitter()
kmf.fit(df['t'], df['Rx']) # t = 时间点, Rx: 0=删失, 1=事件
kmf.plot()
如果你只想显示深蓝色曲线并隐藏浅蓝色置信区间怎么办？
简单：只需使用 km.plot(ci_show=False)。ci_show 中的 ci 表示置信区间。示例：
kaplan_meier_no_ci_example.py
from lifelines.datasets import load_leukemia
from lifelines import KaplanMeierFitter
df = load_leukemia()
kmf = KaplanMeierFitter()
kmf.fit(df['t'], df['Rx']) # t = 时间点, Rx: 0=删失, 1=事件
kmf.plot(ci_show=False)
