Non-collapsibility and built-in selection bias of period-specific and conventional hazard ratio in randomized controlled trials

BMC Medical Research Methodology
Background The hazard ratio of the Cox proportional hazards model is widely used in randomized controlled trials to assess treatment effects. However, two properties of the hazard ratio including the non-collapsibility and built-in selection bias need to
