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 assess central corneal thickness (CCT), as well as the density and morphology of corneal endothelial cells (ECD) in myopic eyes. Methods: A total of 400 patients scheduled for myopic refractive surgery were consecutively enrolled in this study. Preoperative evaluations encompassed endothelial cell density (ECD), average cell area (CA), coefficient of variation (CV), and percentage of hexagonality (HEX), all measured using the Nidek CEM-530. Additionally, central corneal thickness (CCT) was assessed using the Pentacam HR. Ocular biometric parameters, including axial length (AL), were recorded with the IOL Master 700. Each parameter was analyzed based on ocular laterality, age, gender, spherical equivalent (SE), and AL. Results: The analysis revealed that 39% of participants were female, with a mean age of 25.36 ± 6.92 years and a mean SE of -5.06 ± 1.92D. No statistically significant differences in ECD were observed between genders, although males showed slightly higher values for HEX and CCT. No significant differences in CCT, ECD, or corneal endothelial morphology were found among subgroups categorized by SE or AL. Significant negative correlations were observed between age and both ECD ( Conclusions: SE and AL show no significant effect on CCT or corneal ECD and morphology in our refractive surgery candidates. Weak age-CCT/ECD correlations were noted. Gender and ocular laterality effects warrant preoperative evaluation.
