Difference between survdiff log-rank and coxph log-rank Sorry, i forgot to add the data probably is mor clear now, I want to know if adjusting using other covariates I can say that my logrank score test coming from coxph, p=0.0005793 could replace the former survdiff logrank p= 0.619. Thanks and sorry is you find the question too simple, I'm totally newbie in survival analysis
