This holds for any time s > 0 in this example. This exemplifies that the direction of the risk ratio (above or below one) can be opposite of that of the hazard ratio. 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).
