What is the KM plotter? The Kaplan Meier plotter is capable of assessing the correlation between the expression of all genes (mRNA, miRNA, protein, & DNA) and survival in 35k+ samples from 21 tumor types. Applied statistical tools include Cox proportional hazards regression and the computation of the False Discovery Rate.

For this, the Kaplan Meier curve graphically represent the survival rate or survival function. Time is plotted on the x-axis and the survival rate is plotted on the y-axis. The first question is what is the survival rate. Let's look at this with an example.

Throughout this article we will discuss Kaplan-Meier (K-M) estimates in the context of “survival” before the event of interest. Two small groups of hypothetical data are used as examples in order for the reader to clearly see how the process works.

对于生存数据，1958年，E. L. Kaplan 和 Paul Meier 两位教授介绍了一种全新的、解决随访期间右删失 (right censoring) 问题的 生存分析 方法，被称作 Kaplan-Meier方法。 这种方法精确地记录并利用每个个体发生终点事件的具体时间，在任何一个终点事件发生的时间点计算出一个新的、基于之前所有信息的总生存率 (Cumulative survival) 。 相比于之前使用的 寿命表法 （Life-table method），这种方法更加充分地利用了信息，给出更准确的统计量。 同时，作为一种非参数 …

2016年7月1日 · Survival analyses are statistical methods used to examine changes over time to a specified event. K-M is the most frequent survival analysis method used in randomized (phase III and some phase II) medical clinical trials in which the following criteria are met:

The Kaplan-Meier curve (KM curve) is a commonly used tool in survival analysis, primarily for estimating survival rates over a period of time. By analyzing survival time data, it helps researchers understand the survival probability of individuals or groups at different time points.

此次笔记采用Kaplan-Meier法绘制生存曲线，同时比较不考虑其他因素下，不同病理学分期多发性骨髓瘤患者生存曲线。 假设其他各个协变量组间均衡，已知研究变量病理学分期stage（1=I期；2=II期；3=III期），生存结局状态status（0=存活；1=死亡）生存时间time_days（确诊后生存时间，天）。 Kaplan-Meier法也称乘积极限法，SPSS操作可参见《生存分析》，此次笔记示例stata操作。 【1】查看数据基本情况. 分析>>生存分析>>摘要统计，检验和表格>>生存时间数 …

To interpret the K-M curve, we first need to look at the axes. The horizontal axis represents time, usually measured in months or years. The vertical axis represents the estimated probability of an event. So the first step is to identify what is the event of interest and the units of measurement along the axes. 2. Check the shape of the curve.

2024年10月24日 · In this article, let’s see in detail what KM analysis is, how the Kaplan-Meier Curve is built, the math behind calculating the probabilities of survival. But before diving directly into the KM analysis, we shall have a quick and brief walk around on what is survival analysis and basic notations used in the analysis.

In preparing K-M survival analysis, each subject is char-acterized by three variables: 1) their serial time, 2) their status at the end of their serial time (event occurrence or censored), and 3) the study group they are in. These com-ponents may be displayed in a table (Table 1).
