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: To identify associated long-term risk factors of visual field (VF) progression among eyes of primary angle-closure disease (PACD), including primary angle-closure suspect (PACS), primary angle-closure (PAC), and primary angle-closure glaucoma (PACG). Methods: PACD eyes with at least a 10-year follow-up duration were included. VF was tested every 6 months using the 24-2 pattern standard on the Humphrey Field Analyzer. The initial intraocular pressure (IOP) fluctuation and initial visual field index (VFI) slope were calculated based on the first-year follow-up data. Univariable and multivariable Cox proportional hazards regression models were calculated to determine potential risk factors associated with VF progression, as assessed by guided progression analysis. Results: Forty out of 129 eyes with PACD (31.0%) developed VF progression, including two out of 11 PACS eyes (18.2%), nine out of 52 PAC eyes (17.3%), and 29 out of 66 PACG eyes (43.9%). In multivariable Cox models, among PACG eyes, higher IOP fluctuation (hazard ratio [HR] = 1.591; 95% confidence interval [CI], 1.128-2.245) and steeper initial VFI slope (HR = 3.325; 95% CI, 2.046-5.404) were associated with VF progression. Among PACS/PAC eyes, a steeper initial VFI slope (HR = 4.848; 95% CI, 1.627-14.448) was associated with VF progression (P ≤ 0.008). Conclusions: Our findings underscore the importance of monitoring IOP fluctuation in PACG eyes and initial VFI slope in PACD eyes, supporting the implementation of tailored management strategies based on disease severity and refractive status.
