Comparison of safety and effectiveness between 23-gauge and 25-gauge vitrectomy surgery in common vitreoretinal diseases
Fig 2
Visual acuity change from baseline.
Mean visual acuity change from baseline subdivided by gauge system used for surgery (least squares means derived from the mixed models) with 95% confidence limits for patients of treatment group 1 (panel A: vitrectomy and gas tamponade) or group 2 (panel B: vitrectomy without gas tamponade). The numbers at the bottom of the figure show the number of observations / number of eyes / number of patients.
