For all the eyes that were analyzed, the success rate at the final visit was 78% for the IVB group and 56% for the control group, which was marginally significant ( P = 0.057 by chi-square test).
For all the eyes that were analyzed, the success rate at the final visit was 78% for the IVB group and 56% for the control group, which was marginally significant ( P = 0.057 by chi-square test).
For the subgroup where the extent of PAS was less than 50%, the IVB injection showed a protective effect of surgical failure, with a HR of 0.39 and borderline significance ( P = 0.064, per 1-time IVB injection) ( Table 5 ).
When these variables were entered into a multivariate model with backward elimination approach, only PRP and the extent of PAS showed marginal significance (hazard ratio [HR] = 0.40 and 2.25, P = 0.072 and 0.075, resp.).
