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

backgroundGiven the two different kinds of epiretinal membranes, this study aimed to compare both the structural and functional outcomes of lamellar macular holes with and without lamellar hole-associated epiretinal proliferation (LHEP) after surgery.

methodPublications up to July 2020 that compared the surgical outcomes of lamellar macular hole with and without LHEP were included. Forest plots were created by using a weighted summary of proportion meta-analysis. Fixed or random effects models were used on the basis of I2 heterogeneity estimates. Meanwhile, to evaluate the stability of the meta-analysis, a sensitivity analysis was carried out.

resultsEight pertinent publications that contained a total of 176 eyes without LHEP and 173 eyes with LHEP were included. They were all retrospective studies and had a follow-up of at least 6 months. In all studies, the preoperative best corrected visual acuity showed no significant differences between the two groups, and the visual acuity improved in both groups after surgery. The pooled result for the improved best corrected visual acuity was 0.18 (95% confidence interval (CI), 0.10 to 0.26; P < 0.01) between the with and without LHEP groups. The restored ellipsoid zone odds ratio was 0.80 (95% CI, 0.26 to 2.44; P = 0.69) for the group with LHEP compared to the group without LHEP.

conclusionPatients without LHEP had better postoperative visual acuity than patients with LHEP. No significant difference in restored ellipsoid zone was found between the two groups.
