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

purposeThis study aimed to evaluate changes in visual acuity before and after the development of submacular hemorrhage secondary to neovascular age-related macular degeneration (AMD) and to compare the visual outcomes between patients with and without hemorrhage.

methodsThis retrospective observational study included 124 patients with neovascular AMD. Patients who developed a submacular hemorrhage involving the fovea were included in the hemorrhage group (n = 55). Patients with no sign of submacular hemorrhage during the follow-up period were included in the no-hemorrhage group (n = 69). Visual outcomes were compared between the two groups.

resultsThe logarithm of the minimal angle of resolution best-corrected visual acuity (BCVA) before the development of submacular hemorrhage, once the hemorrhage had developed, and 6 months after the development of hemorrhage was 0.59 ± 0.45, 1.24 ± 0.57, and 0.99 ± 0.64, respectively. BCVA was significantly worse 6 months after the hemorrhage compared to before the hemorrhage (

conclusionsVisual acuity was significantly worse after hemorrhage than before hemorrhage, even after treatment. In addition, patients with submacular hemorrhage had markedly worse visual outcomes than patients without hemorrhage. This result suggests that the development of hemorrhage during the treatment course of neovascular AMD has a devastating effect on visual prognosis.
