WebApr 9, 2016 · When considering the hazard ratio, it is best to obtain this by fitting a Cox proportional hazards model. If you do not adjust for outcome heterogeneity caused by any other variables than the grouping variable, your regression model would contain one binary predictor. The output will be a log hazard ratio and its standard error. WebThe primary outcomes were 1-year overall survival (OS) and 1-year progression-free survival (PFS), estimated by calculating the 95% confidence interval (CI) for the combined odds ratio (OR) and hazard ratio (HR). Secondary outcomes estimated using OR were disease objective response rate (DORR) and incidence of adverse events.
