A Randomized Controlled Trial of Conbercept Pretreatment before Vitrectomy in Proliferative Diabetic Retinopathy

Figure 2

Bar graph showing incidence of early and late recurrent VH with or without conbercept pretreatment after surgery. Subgroup pairwise analysis showed significant differences in early recurrent VH incidence between preoperative IVC group and control group. However, there was no statistically significant difference in late recurrent VH in both groups (, , resp.). VH: vitreous hemorrhage; IVC: intravitreal conbercept.
