Figure 1From: Comparison of risks of cardiovascular events in the elderly using standard survival analysis and multiple-events and recurrent-events methodsSummary of hazard ratios and confidence intervals of risk factors. The summary includes the following survival models: Model 1 (time-to-first-event model, single event type); Model 2 (recurrent event model); Model 3 (multivariate event-type model); Model 4 (multivariate recurrent event model). Circles represent hazard ratios. Confidence intervals for Model 4 are shown as thicker lines.Back to article page
