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 compare the safety and efficacy of 25-gauge pars plana vitrectomy (PPV) with either platelet-rich plasma (PRP) or inverted internal limiting membrane (ILM) flap for the treatment of large macular hole. Methods: Pseudophakic patients with idiopathic macular holes with a minimum diameter (MD) of 600-1500 μm were randomized into two groups (30 patients each): 25-gauge PPV with either inverted ILM flap (group A) or PRP (group B). Results: Mean MD in groups A and B were 803.33 ± 120.65 μm and 784.73 ± 120.10 μm, respectively (P = 0.552). Mean base diameter in groups A and B was 1395.17 ± 240.57 μm and 1486.90 ± 281.61 μm, respectively (P = 0.180). The median presenting best-corrected visual acuity (BCVA) was logMAR 0.78 (range 0.78-1.00) and logMAR 0.78 (Range 0.60-1.00) in groups A and B, respectively (P = 0.103). Anatomical closure was achieved in 90% (n = 27/30) and 93.3% (n = 28/30) eyes in groups A and B, respectively (P = 0.158). Type 1 closure was achieved in 76.7% (n = 23/30) and 83.3% (n = 25/30) eyes in groups A and B, respectively. Median BCVA at postoperative 3-month in groups A and B was logMAR 0.60 (range 0.48-0.60) and logMAR 0.60 (range 0.48-0.78), respectively (P = 0.312). The average visual improvement was 2.0 and 2.5 early treatment diabetic retinopathy study (ETDRS) lines in groups A and B, respectively (P = 0.339). None of the patients developed postoperative exaggerated inflammatory reactions. Conclusion: Using platelets for the treatment of large macular holes is as safe and effective as an inverted ILM flap.
