Cumulative incidence curve for elective cholecystectomy for the study cohort using a piecewise regression model (least squares non-linear regression). Patients were censored for death or emergency cholecystectomy. Of these patients undergoing elective cholecystectomy, 79.6% underwent cholecystectomy at three months and 88.9% underwent cholecystectomy at twelve months. For elective cholecystectomy, the joint point/inflection point (represented by the dotted vertical line) was 2.44 months (95% CI 2.39, 2.48).
