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.
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 investigate the relationship between central retinal vessel trunk movement and lamina cribrosa pores (LCPs) movement during acute intraocular pressure (IOP) elevation and assess whether vessel trunk movement may serve as a potential indicator of LCPs movement.
methodsDuring a dark room prone provocative test (DRPPT), angle-closure suspects remained prone in a dark room for 2 h. Tonometry, optical coherence tomography, and fundus photography were performed at baseline and within 5 min after DRPPT. Movement distance and direction of the central retinal vein trunk (CRVT), central retinal artery trunk (CRAT), and LCPs were measured.
resultsNinety-four eyes of 56 participants were included. IOP increased from 16.3 ± 3.3 to 23.4 ± 4.3 mmHg. Mean movement distances were 23.3 ± 14.2 μm for CRVT and 21.5 ± 13.9 μm for CRAT. In 38 eyes with identifiable LCPs, mean absolute distance differences between CRVT/LCPs and CRAT/LCPs were 9.1 ± 8.2 and 9.5 ± 8.2 μm, respectively, and mean absolute angular differences were 22.5 ± 18.0° and 22.9 ± 17.5°. CRVT and CRAT movement distances were significantly correlated with LCPs movement distance, while circular-circular analysis showed strong associations between movement directions (both r
conclusionCentral retinal vessel trunk movement was correlated with LCPs movement during acute IOP elevation in eyes with visible LCPs, although individual prediction remained variable.
