Hazard Ratios Comparing Risk of Stroke or Death Between CSA and CEA: The left pane shows partial likelihood estimators of a 3 piece time-dependent constant hazard ratio (steps at 1 and 6 months, in a dashed line) and a log-linear time-dependent hazard ratio (solid line). The pane on the right shows the corresponding estimators based on the instrumental variable we proposed
