ch.15 Logrank trend test

 

A choice of the same variable, but for the trend test, the population variable must be configured with at least 3.

 

The survival curve is not drawn, so we use what we made earlier. You should first look at the picture, then look at the value of p according to the illustration and write down the names of the groups in alphabetical order. In other words, the results should be named A, B, C, from small to large groups, to test for the presence of trend in that order. This is not to test difference, but to increase or decrease.
