Patients who crossed over had their hazard of outcome determined by that of the standard group, and were analysed accordingly by the AT approach.
Hazard ratios of outcomes under study are calculated for each parameter estimate as well as 95% confidence intervals.
Table 3 presents the time dependent adjusted hazard ratios of outcomes with antithrombotic treatment during follow-up in patients surviving the first 90 days after gastrointestinal bleeding.
This means that the cumulative incidence of patients dying and being transplanted was higher in larger centres, even though centre volume did not change the underlying (cause-specific) hazard of these outcomes.
When interarm difference was analysed as a continuous variable, the hazard of all outcomes increased by a consistent 5% for each 1 mm Hg increment in interarm difference in systolic blood pressure after adjustment.

A composite outcome measure for morbidity was employed to maximise the number of events that could be included in the analysis and avoid the need to select a single morbidity as a primary outcome measure; however, a hazard of composite outcome measures is the assumption that the significance of the result applies to all components.
However, for RCTs, explicit formulas exist to estimate statistical power when using a Cox proportional hazards model to estimate the effect of treatment on the hazard of an outcome [ 11].
As above, we allowed the following factors to vary: the sample size of the RCT, the prevalence of treatment (Ptreat - the proportion of subjects randomly assigned to the active treatment arm of the RCT), and the magnitude of the effect of treatment on the hazard of the outcome (βtreat - the marginal log-hazard ratio).
However, a hazard of composite outcome measures is the assumption that the significance of the result applies to all components.
