The median is an important summary measure for survival data. A confidence interval for the median estimated from censored survival data is easily obtained from the pointwise confidence interval around the Kaplan–Meier estimator. A test for equality of k medians is also given. Keywords: survival ...
The Kaplan-Meier survival curves for the length of time until death for the treatments of palliative chemotherapy and supportive care were presented (figure). The median survival time was estimated to be 8.0 months in the supportive care group and 11.7 months in the chemotherapy group.1 Kaplan...

mortality were used to calculate the survival time, and the estimates of the cumulative proportion surviving were based on Kaplan‑Meier procedures (19)... S Motoaki,K Chihiro,I Seiji - 《Molecular & Clinical Oncology》 被引量: 1发表: 2014年 653. Direct Identification of Microorganisms in Po...
This produces a discrepancy between the true progression time and the observed progression time. When the observed progression time is considered as the true progression time, a positively biased PFS is obtained for some patients, and the estimated survival function derived by the Kaplan–Meier ...
Kaplan-Meier Curves - length of time from study entry to disease end-point for a treatment and control group - from this curve, we can derive: -> median time (time at which 50% of cases resolve) -> mean (average resolution time) ...
aThe duration of time to an event will be summarized by Kaplan-Meier plot, and presented as event number, percentage, 95% confidence interval for percentage, mean, median and 95% confidence interval for median. 时间的期间到事件将由卡普兰Meier剧情总结,并且被提出当活动编号、百分比、95%信赖区间为...
The exact median life expectancy (or the agetfor which Lt = 0.5) was calculated via linear interpolation, unless one of the Kaplan Meier estimates fell exactly on 0.5. That is, if [x0, L0] is the smallest [survival time, survival probability] pair greater than Lt = 0.5, and...

Visualizing length of survival in time-to-event studies: a complement to Kaplan-Meier plots. In the RE01 trial, median survival of patients treated with interferon was 3.0 months (95% confidence interval = 0.3 to 5.5 months) longer than that ... Patrick,Royston,KB Mahesh,... - 《Journal...
