Figure 1 Unadjusted average PLOS (days) and unadjusted rate of major complications (percentage) are measured on the horizontal and vertical axes, respectively. Squares represent the 140 procedure types with n greater than 10. PLOS, Postoperative length of stay.

Figure 2 The proportions (%) of Any Major Complication and of Any Major Complication or Mortality are measured on the horizontal and vertical axes, respectively. The squares represent the 140 procedure types with n greater than 10.

Figure E1 The relationship between the number of categories and the degree of within-category homogeneity. Within-category homogeneity is defined as 1 minus the ratio of within-category variance to total variance of procedure-specific morbidity estimates.
