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

Purpose: To investigate the relationship between posterior vitreous detachment (PVD) status and fibrovascular membrane (FVM) angio-fibrotic transformation following anti-VEGF therapy in advanced proliferative diabetic retinopathy (PDR), and their combined impact on disease progression and visual outcomes. Methods: This prospective real-world study enrolled 165 treatment-naïve PDR patients with vitreous hemorrhage (VH) and FVM who received intravitreal anti-VEGF injection followed by panretinal photocoagulation(PRP) when possible. PVD status and FVM characteristics were monitored during a median follow-up of 13.0 months. Cox proportional hazards and Kaplan-Meier analyses evaluated factors influencing visual prognosis and timing of surgical intervention. Results: FVM fibrosis occurred in 43% of patients, with distinct PVD-dependent patterns: predominantly in complete PVD cases, moderately in partial PVD, and rarely without PVD. Multivariate analysis identified macular involvement as the strongest risk factor for poor visual outcomes (HR=3.65), while PVD (HR=0.37) and FVM fibrosis (HR=0.023) were strongly protective. Patients with both PVD and FVM fibrosis maintained stable vision longest (median 28.5 months) and demonstrated significantly longer surgery-free survival (28.3 months) compared to those without either condition (3.2 months, p<0.0001), who frequently presented with vitreoschisis and recurrent VH disproportionate to visible FVM grade. Conclusion: PVD status critically determines the clinical manifestation and prognosis of post-anti-VEGF FVM fibrosis in PDR. This PVD-dependent pattern challenges the conventional view that FVM fibrosis inevitably leads to "Crunch syndrome" and creates a risk stratification framework that can guide individualized surgical timing decisions, potentially improving functional outcomes in advanced PDR.
