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
Purpose: To develop a normative profile for choroidal vortex vein systems based on ultra-widefield OCT angiography (UWF-OCTA) in a healthy Chinese population. Design: A cross-sectional, multicenter study. Participants: A total of 515 eyes of 515 Chinese adults (515 healthy eyes) aged ≥20 years were recruited from the Choroidal Vortex Vein System Study. Methods: All participants underwent comprehensive ophthalmic examinations. The 2-dimensional and 3-dimensional choroidal parameters of the vortex vein system were measured in each vortex vein drainage quadrant (24 × 20 mm Main Outcome Measures: Choroidal thickness, choroidal vascularity index (CVI), choroidal vascular volume (CVV), and choroidal stromal volume (CSV). Results: The fifth and 95th percentile values of the choroidal parameter dataset for the peripheral choroidal vortex vein system were set. The mean values of the peripheral choroidal vortex vein system parameters (choroidal thickness, CVI, CVV, and CSV) decreased with age, with a significant decline after 50 years. An association was observed between an increased axial length elongation and a thinner choroid layer in the macular region and the ST drainage system (all Conclusions: We report a normative choroidal parameter dataset for the peripheral choroidal vortex vein system in a large Chinese cohort. Choroidal vessels and stroma in vortex vein drainage systems decrease with age, more remarkably after the age of 50 years.
