Fig. 3

Association of adverse events and surgeon volume by facility volume. Each panel of the figure illustrates the volume-outcome relationship for a specific type of eye surgery by above (high) or below (low) median facility volume (weighted by procedure), depicting the regression-adjusted odds ratios and corresponding 95% confidence intervals of adverse outcomes across surgeon-volume quintiles. Panel a plots the relationship for cataract surgeries, panel b plots the relationship for retinal detachment surgeries, and panel c plots the relationship for traditional glaucoma surgeries. The outcome is a binary indicator for an adverse outcome within 30 days of a procedure. For cataract surgeries, volume quintiles were: 0–105, 106–200, 201–315, 316–520, and 521–1360 surgeries in the last year. For retinal detachment surgeries, volume quintiles were: 0–25, 26–45, 46–65, 66–100, and 101–275 surgeries. For traditional glaucoma surgeries, volume quintiles were: 0–5, 6–20, 21–40, 41–70, and 71–180 surgeries.
