Evaluating the predictive relationship between manifest refractive astigmatism, topographic astigmatism, and ocular residual astigmatism: A comparative study.

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
BackgroundThe interaction between manifest refractive astigmatism and topographic astigmatism is critical in planning refractive surgery. This study aimed to investigate the predictive relationship between manifest refractive astigmatism and topographic astigmatism across different age groups.MethodsThis is a retrospective observational study comprising 149 patients. Manifest refractive astigmatism was evaluated through subjective refraction methods, and topographic astigmatism was measured using corneal topography. Inclusion criteria were patients aged 20-41 years without a history of ocular surgery or severe corneal pathology. The main outcome was to determine the relationship between manifest refractive astigmatism and topographic astigmatism and to test whether manifest refractive astigmatism served as a reliable predictor of topographic astigmatism in two age groups (≤30 and >30 years).ResultsPearson correlation analysis revealed a strong positive correlation between manifest refractive astigmatism and topographic astigmatism (
