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: This study evaluates retinal volume in the macula and peripheral retina in patients with nonproliferative diabetic retinopathy (NPDR), with and without diabetic macular edema (DME), using widefield swept-source OCT (SS-OCT). Design: Retrospective observational study. Participants: A total of 98 eyes were included: 30 from patients with NPDR without DME (DME-), 38 from patients with NPDR with DME (DME+), and 30 from age- and sex-matched healthy controls. Methods: OCT examinations used SS-OCT (Xephilio OCT-S1; Canon) to capture 23 × 20 mm (1024 × 128 A-scans) cube images. Retinal volume was calculated for each sector in a 9-sector grid defined by concentric circles (1 mm, 6 mm, and 20 mm in diameter) centered on the fovea and divided into four quadrants: superior, inferior, nasal, and temporal. The macular region was defined within a 6-mm diameter, whereas the peripheral retina spanned 6 mm to 20 mm. Main Outcome Measures: Macular and peripheral retinal volumes measured from SS-OCT images in each group. Results: A total of 98 eyes were analyzed (control: 30; DME-: 30; DME+: 38). Macular retinal volume was 8.46 ± 0.49 mm Conclusions: Our findings indicate that retinal volume increases in both macular and peripheral regions in DME, particularly as NPDR severity progresses.
