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.

2 · The registry

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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeTo appraise the efficacy of anti-vascular endothelial growth factor (anti-VEGF) drugs as an adjunctive treatment before pars plana vitrectomy (PPV) in patients suffering from proliferative diabetic retinopathy (PDR).

methodsRelevant studies published up to December 2024 were retrieved from PubMed, Embase, Cochrane, and Web of Science. Data analysis was implemented by means of Stata version 15.0. Weighted mean difference (WMD), risk ratio (RR), and their corresponding 95% confidence intervals (CIs) were estimated.

results17 randomized controlled trials (RCTs) were incorporated. The meta-analysis revealed that preoperative anti-VEGF treatment in PDR patients can reduce intraoperative vitreous hemorrhage (VH) (RR = 0.38, 95% CI 0.28, 0.52, P < 0.01), decrease the incidence of iatrogenic retinal tears (RR = 0.56, 95% CI 0.43, 0.72, P < 0.01), and shorten surgical duration (WMD =  - 24.04, 95% CI - 30.37, - 17.71, P < 0.01). Additionally, this treatment improves postoperative best-corrected visual acuity (BCVA) (WMD =  - 0.18, 95% CI - 0.28, - 0.09, P < 0.01), reduces both early (RR = 0.63, 95% CI 0.45, 0.89, P = 0.009) and late-stage (RR = 0.43, 95% CI 0.26, 0.70, P = 0.001) VH, and accelerates the absorption of recurrent VH.

conclusionsThe preoperative use of anti-VEGF agents in PPV can reduce the incidence of intraoperative VH and retinal tears, thereby facilitating a quicker and easier surgical procedure.
