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 compare the functional and anatomical outcomes of the inverted internal limiting membrane (ILM) flap covering and stuffed techniques in primary macular hole (MH) surgery.

methodsThis retrospective case series included 57 eyes that underwent inverted ILM flap surgery by a single surgeon (covering, n = 33; stuffed, n = 24). Best-corrected visual acuity (BCVA) and optical coherence tomography findings, including restoration of the external limiting membrane (ELM) and ellipsoid zone (EZ), were assessed preoperatively and at 1 and 6 months postoperatively.

resultsThere were no significant differences in preoperative characteristics or MH closure rates between groups. BCVA improved significantly in both groups postoperatively; however, BCVA was significantly better in the covering group at 1 month (P = 0.005) and 6 months (P = 0.001). Restoration of the ELM and EZ was more frequent in the covering group at 1 month (ELM, P < 0.001; EZ, P = 0.002) and 6 months (ELM, P < 0.001; EZ, P = 0.001).

conclusionAlthough both techniques achieved comparable anatomical closure, the covering method provided superior visual and outer retinal recovery for a wide range of macular holes, including medium-to-large cases. These findings suggest that the covering technique may be preferable as a standard approach for primary MH surgery.
