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

purposeThe aim of this study was to evaluate the efficacy of XEN

methodsIn this retrospective, observational, single-centre study, patients with POAG or XFG underwent implantation of the XEN

resultsSeventy-nine eyes of 63 patients with open-angle glaucoma were included in the study (71% POAG, 29% XFG). Before surgery, mean IOP was 23.4 ± 7.9 mmHg. IOP was 14.6 ± 3.6 mmHg 12 months postoperatively (-31% from baseline, 95% CI -42% to -20%, n = 30, p < 0.001) and 14.8 ± 4.4 mmHg 24 months postoperatively (-29% from baseline, 95% CI -30% to -41%, n = 28, p < 0.001). Mean number of IOP-lowering medications was significantly reduced from 2.7 ± 1.1 before surgery to 1.0 ± 1.2 (-69%, 95% CI -89% to 46%, p < 0.001) 12 months after surgery and 1.0 ± 1.2 (-64%, 95% CI -91% to -36%, p < 0.001) at 24 months after surgery. Complete surgical success was achieved in 39% (12M) and 34% (24M) of patients and qualified success in 29% (12M) and 27% (24M). 13 (16%) eyes were classified as complete surgical failure. In 62% of the patients needling procedures had to be performed.
