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

This study aims to characterize diurnal changes in corneal geometry of the anterior and posterior cornea in healthy eyes using global and sector-based metrics, and to explore their associations with lifestyle-related factors. A prospective observational study of 109 eyes was conducted, measuring intraocular pressure (IOP), corneal thickness, volume, and global/sector-based keratometry at five time points over a 10 h period, alongside a lifestyle questionnaire. Results revealed significant diurnal decreases in IOP, central and minimum corneal thickness, and corneal volume (
