WebHazardRatio is a SAS macro to generate Wald, Peto’s, and score confidence intervals (CIs) for the log hazard ratio in randomized clinical trials. The point estimate, standard error, and p-value for each method is also generated. The Wald CI is based on the maximum partial likelihood estimator (MPLE) and the corresponding Fisher information matrix. WebOct 28, 2024 · The HAZARDRATIO statement identifies the variable whose hazard ratios are to be evaluated. If the variable is a continuous variable, the hazard ratio compares the hazards for a specified change (by default, an increase of 1 unit) in the variable. For a CLASS variable, a hazard ratio compares the hazards of two levels of the variable.

We evaluated the association of general obesity measured … Webup, the proportional-hazards assumption of constant hazard ratios is frequently violated. One alternative is to t an interaction between covariates and a prespeci ed function of time, implemented as a time-dependent covariate. This e ectively creates a time-varying coe cient that is easily estimated in software such as SAS and R. However, the usual
