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 clinical features and treatment outcomes of bilateral myopic macular neovascularization (mMNV).

methodsThis single-centre retrospective study included patients with bilateral high myopia who were newly diagnosed with unilateral mMNV (first eye) between January 2008 and July 2020. Patients who presented with mMNV or macular atrophy suggestive of previous mMNV in the fellow eye (second eye) were excluded. Patients were classified into unilateral or bilateral groups based on mMNV development in the second eye during follow-up of >36 months.

resultsNinety-three patients were included with the mean age of 55.4 ± 13.1 years and 71 (76.3%) were female. The mean baseline spherical equivalent was -13.0 ± 5.5 diopters. Of total, 21 (22.6%) developed mMNV in the second eye during the mean follow-up period of 95.1 ± 38.9 months; the cumulative probabilities were 16.2% at 5 years and 28.9% at 10 years after the first eye mMNV development. The uninvolved second eyes of the unilateral group had shorter axial length (AL) and greater subfoveal choroidal thickness than the eyes with mMNV. The unilateral group showed a greater interocular difference in AL than the bilateral group (p < 0.001). The presence of lacquer cracks in the second eye was identified as a significant risk factor for the second eye mMNV development (HR = 5.64, 95% CI: 1.59-20.08, p = 0.008). In the bilateral group, the second eye showed less vision improvement after anti-VEGF treatment, but the final visual acuity and cumulative probability of fovea-involving mMNV-related chorioretinal atrophy did not differ between the eyes.

conclusionsApproximately 30% of bilateral high myopic patients with unilateral mMNV are estimated to develop mMNV in the second eye over a period of 10 years. The presence of lacquer cracks in the second eye was a significant risk factor. The first and second eyes showed comparable treatment outcomes.
