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
To investigate the correlation between the corneal biomechanical properties of cataract patients measured by Corvis-ST and surgically induced corneal astigmatism (CSIA) derived from anterior segment swept-source OCT (CASIA2). A total of 149 eyes from 149 patients received phacoemulsification with a 2.2-mm clear corneal incision at the 135° were involved. Before surgery, all patients were examined by Corvis-ST for dynamic corneal response parameters (DCRs). The total corneal astigmatism was measured using CASIA2 before the operation and at 1 month follow-up. CSIA was obtained using Alpins vector analysis. After adjustment for age, central corneal thickness, and biomechanically corrected intraocular pressure, partial correlation analysis was used to analyze the correlation between the CSIA and DCRs. The centroid of CSIA was 0.48 D @ 43°, with a magnitude of 0.75 ± 0.44 D. The age of the patient was positively correlated with the magnitude of CSIA (r = .22, P = .009). The partial correlation analysis revealed that deformation amplitude ratio (DA ratio, r = -.17, P = .045) and integrated radius (IR, r = - .20, P = .014) were both negatively correlated with the magnitude of CSIA. The magnitude of CSIA can be expressed as: [Formula: see text]. DA ratio and IR were negatively correlated with the magnitude of CSIA in 2.2-mm cataract surgery indicating an association of increased corneal stiffness with increased magnitude of CSIA.
