(Uncensored) includes cases that did not reach the end of the study as well as cases that reached the end of the study, and in both scenarios we mark them (0) in the Excel sheet. Is my understanding true?

[@beingnormal1899]

When calculating the variance what does ni mean?

[@sudhakarpalanisamy6518]

Thanks for the detailed explanation. I saw that the p value for log rank is taken as 0.003. Can you clarify please?

[@datatab]

Hello, thank you for your feedback! Where does the 0.003 occur or what should I explain?
