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 assess the retinal features in eyes with postoperative metamorphopsia (POM) following rhegmatogenous retinal detachment (RRD) repair using multimodal imaging (MMI).

methodsIn this cross-sectional; case-control study, patients after successful RRD repair following 25-gauge vitrectomy, clear vitreous cavity, and corrected distance visual acuity (CDVA)>20/200 were categorized using Amsler chart: cases with POM and controls without POM. MMI was performed on swept-source platform (Triton, Topcon Inc) and the confocal scanning laser ophthalmoscope system (Spectralis HRA, Heidelberg). The measures assessed were CDVA, morphological features on optical coherence tomography, autofluorescence, and multicolor imaging (MCI).

resultsThirty-nine eyes were included in each group. Cases had greater number of eyes with total RRD (P = 0.029) preoperatively; abnormal foveal contour (P = 0.036), ellipsoid zone (EZ) disruption (P < 0.001) and poorer postoperative CDVA (P = 0.046) as compared to controls. Outer retinal folds and retinal shift (unintentional translocation of retina after reattachment surgery for RRD) did not differ significantly between the groups (P = 0.48 and 0.35, respectively). On MCI, the distribution of detected ERM was similar between the groups (P = 0.25). Postoperative CDVA was significantly worse in eyes with POM.

conclusionPOM is affected by extent of RRD, postoperative foveal contour, and EZ status but not by retinal shift.
