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 compare bleb vascularity changes using optical coherence tomography angiography (OCT-A) between mitomycin-C (MMC)-augmented trabeculectomy and phacotrabeculectomy and to determine whether bleb vascularity measurements during preoperative and early postoperative periods could act as surrogate parameters to predict surgical outcomes.

methodsWe retrospectively reviewed data for 72 eyes from 72 glaucoma patients who underwent MMC-augmented trabeculectomy with/without cataract surgery. Bleb area scans were obtained using OCT-A during the preoperative period; 1, 2, 4, and 6 weeks postoperatively; and 2, 4, and 6 months postoperatively. For conjunctival vascularity analysis, a semi-automated program was used to calculate color and brightness densities of the selected area.

resultsColor and brightness densities were decreased in the trabeculectomy group during all periods but not in the phacotrabeculectomy group at 4 and 6 weeks, as well as 2, 4, and 6 months postoperatively. Color and brightness densities were significantly higher in the phacotrabeculectomy group than in the trabeculectomy group after 6 weeks and 2, 4, and 6 months postoperatively. A Kaplan-Meier survival graph indicated that intraocular pressure differed according to glaucoma type but not surgery type. Logistic regression analysis revealed that brightness density 1 week postoperatively was correlated with reoperation.

conclusionsChanges in conjunctival vascularity density measured by OCT-A differed according to the surgical method. Following trabeculectomy with MMC, brightness density 1 week postoperatively may be a predictive index for surgical outcomes.
