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

The aim of the study was to evaluate the influence of vitreomacular interface configuration on treatment outcomes after intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (AMD).The Pubmed, Embase, and Cochrane Central Register of Controlled Trials databases were searched to identify relevant prospective or retrospective studies that evaluate the influence of vitreomacular adhesion (VMA) or vitreomacular traction (VMT) on functional and anatomical outcomes in neovascular AMD patients treated with anti-VEGF agents. The outcome measures were the mean change in best corrected visual acuity (BCVA) from baseline, the mean change in central macular thickness (CMT) from baseline, and the mean injection numbers of anti-VEGF treatment from baseline.In total, 9 studies were selected for this meta-analysis, including 2156 eyes (404 eyes in the VMA/VMT group and 1752 eyes in the non-VMA/VMT group). In neovascular AMD patients treated with anti-VEGF agents, the VMA/VMT group was associated with poorer visual acuity gains and CMT reductions at 1 year (WMD [95% CI], -6.17 [-11.91, -0.43] early treatment diabetic retinopathy study (ETDRS) letters, P = .04; WMD [95% CI], 22.19 [2.01, 42.38] μm, P = .03, respectively). There was no significant difference between 2 groups in the mean BCVA change and the CMT change over 2 years (WMD [95% CI], -5.59 [-21.19, 10.01] ETDRS letters, P = .48; WMD [95% CI], 6.56 [-24.78, 37.90] μm, P = .68, respectively). There was no significant difference in the mean injection numbers between 2 groups at 1 year (WMD [95% CI], 0.36 [-0.19, 0.90], P = .21), whereas the VMA/VMT group had a significantly higher mean injection numbers over 2 years (WMD [95% CI], 1.14 [0.11, 2.16], P = .03).The limited evidence suggests that vitreomacular interface configuration have a significant influence on the visual acuity gain and CMT reduction at 1 year, injection numbers at 2 years in neovascular AMD patients treated with anti-VEGF agents. However, the results of this meta-analysis should be interpreted with caution because of the heterogeneity among study designs. Eyes with VMA/VMT on optical coherence tomography at baseline may require more intensive treatment with decreased response to anti-VEGF agents.
