Fig. 5 — Scatterplots and linear regression analysis for the subgroup of cases where only trabeculotomy without cataract surgery was performed (n = 55): TO opening versus percent IOP reduction (A) or ΔIOP (B). Similar to the result of the whole study population, the slope of the linear regression line was close to zero and the 95% confidence interval of the slope included zero for both plots, indicating no correlation between TO opening and IOP reduction. C) ACD versus IOP reduction was also not significantly correlated. D) The slope of the regression line between ACD and TO opening was significantly non-zero (p = 0.03)
