1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract

backgroundTo compare the efficacy and safety of preoperative intravitreal injections of ranibizumab and conbercept in Chinese proliferative diabetic retinopathy (PDR) patients.

methodsThis prospective randomized controlled trial enrolled 90 eyes of 80 patients with PDR. Forty-four eyes of 40 patients that received intravitreal ranibizumab (IVR) injections (0.5 mg/0.05 mL) before vitreous surgeries were assigned to the IVR group. Forty-six eyes of 40 patients that received intravitreal conbercept (IVC) injections (0.5 mg/0.05 mL) before vitreous surgeries were assigned to the IVC group. Intraoperative and postoperative indices were assessed for further comparison between the two groups.

resultsThere were no statistically significant differences in all surgery indices, including intraoperative indices (surgery time, P = 0.225; intraoperative bleeding, P = 0.808; endodiathermy use, P = 0.693; incidence of iatrogenic retinal breaks, P = 0.740; relaxing retinotomy, P = 0.682; retinal reattachment, P = 0.682 and silicone oil tamponade, P = 0.814) and postoperative indices (postoperative vitreous hemorrhage (VH), P = 0.808; neovascular glaucoma (NVG), P = 0.964; recurrent retinal detachment, P = 0.531; postoperative fibrovascular proliferation progression, P = 0.682 and reoperation, P = 0.955) between the two groups. There were no statistically significant differences in best-corrected visual acuity (BCVA) at each follow-up visit (P = 0.939, 0.669, 0.741 and 0.717, respectively) or in central retinal thickness (CRT) (P = 0.976, 0.699, 0.551 and 0.686, respectively). As for safety profile, both groups had no ocular or system adverse events during the observation period.

conclusionsIVR and IVC as a pretreatment of vitrectomy had similar efficacy and safety profile for Chinese PDR patients.
