I'm trying to derive the Stratified unadjusted Cox model Hazard ratio and confidence intervals. The specs are such:   Hazard ratio as a treatment effect measure will be derived from the Cox proportional hazards model using SAS procedure PHREG. The stratified unadjusted Cox model will be used (where the baseline hazard function is allowed to vary across strata) for the primary analysis, i.e. the MODEL statement will include the treatment group variable as the only covariate and the STRATA statement will include stratification variables. PROC PHREG data=dataset; MODEL survtime*censor(1)=trt / TIES=EXACT; STRATA stratum1 .. <stratum k>; RUN; /* survtime represents variable containing event/censor times;    censor represents censoring variable (1=censored, 0=event);    trt represents treatment group variable;    stratum1 to stratumk represent stratification variables */ Hazard ratio with two-sided 95% confidence interval will be based on Wald test.       I need to capture the ods output for hazard ratio and confidence intervals into a dataset for reporting. This is the current code:             ODS TRACE ON;         ODS OUTPUT ;         proc phreg data = pop3;         model months*event(0) = TRT01PN  TIES=EXACT;         STRATA STRVAL1 STRVAL2 STRVAL3 ;         run;         ODS OUTPUT CLOSE;         ODS TRACE OFF;     Which ODS output dataset(s) need to be captured and do the values require extra code to derive?   Thank you! ...

  Hello,   I'm trying to derive the p-value for a stratified log-rank test using lifetest. The specs are such:   A stratified log-rank test will be used to test the equivalence hypothesis of survival distributions. The stratification factors are the randomization stratification factors. The LIFETEST procedure in SAS with the TIME statement including a variable with survival times and a (right) censoring variable, with STRATA statement for the stratifying variable and the GROUP option for identifying treatment arms will be used to obtain one sided p-value from log-rank score test. The implementation is as follows. PROC LIFETEST data=dataset METHOD=KM CONFTYPE=LOGLOG;      TIME survtime*censor(1);      STRATA stratum1 stratum2 stratum3 / GROUP=trt; RUN; /* stratum1 stratum2 stratum3 represents the 3 stratum variables (to be included for stratified analysis only);    survtime represents variable containing event/censor times;    censor represents censoring variable (1=censored, 0=event);    trt represents treatment arm variable; */   I need to capture the ods output into a dataset for reporting. This is the current code:   ODS TRACE ON; ODS OUTPUT ;     PROC LIFETEST data=pop3_sall METHOD=KM CONFTYPE=LOGLOG  ;      Time months*event(0);      STRATA STRVAL1 STRVAL2 STRVAL3 / GROUP=TRT01PN ;     RUN; ODS OUTPUT CLOSE; ODS TRACE OFF;   Which ODS output dataset needs to be captured and does it require extra code to derive the p-value?   Thank you! ...
