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 evaluate the impact of membrane peeling for idiopathic epiretinal membrane (iERM) on ganglion cell–inner plexiform layer (GCIPL) thickness in eyes with and without primary open-angle glaucoma (POAG).

methodsA total of 120 eyes (mean age 67.5 ± 10.0 years, female: 59%) were divided into four groups (n = 30 each): (1) POAG with iERM that underwent surgery, (2) non-glaucomatous with iERM that underwent surgery, (3) POAG without iERM, and (4) healthy control. Patients with iERM underwent pars-plana vitrectomy (PPV) with ERM and internal limiting membrane (ILM) peeling. GCIPL thickness within a 4 × 4.8 mm elliptical area was measured using Cirrus OCT (ZEISS, Dublin, CA) at baseline, 6 months, and 12 months postoperatively. Data collected included demographic and clinical parameters, best corrected visual acuity (BCVA), and intraocular pressure (IOP).

resultsA significant three-way interaction was observed between glaucoma, surgery, and time. POAG with iERM that underwent membrane peeling demonstrated greatest thinning, with mean change of − 9.40 μm at 6 months (95% CI: −15.07, − 3.73) and − 10.37 μm at 12 months (95% CI: −15.77, − 4.97), compared to all other groups (p < 0.001). BCVA significantly improved in non-glaucomatous eyes that underwent membrane peeling (p = 0.005), while remaining stable in the other groups. IOP remained stable across all time points.

conclusionsPPV with ILM and ERM peeling is associated with significant GCIPL thinning in glaucomatous eyes. These findings suggest a synergistic effect between glaucoma and surgical intervention, underscoring the need for caution when considering ILM peeling in glaucomatous patients.
