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 investigate the distribution of normative data for higher-order aberrations (HOA) among younger and older populations and identify their correlations with age, gender, and refractive errors. Methods: This study analyzed healthy, phakic, treatment-naïve eyes from Caucasian participants examined at three European centers between July 2019 and July 2022. Total eye and corneal HOA were analyzed using a novel corneal tomographer with an integrated Hartmann-Shack aberrometer. Simple correlation analysis was conducted using the Pearson correlation coefficient, assuming a linear model. Results: A total of 1075 eyes were analyzed. Mean age and spherical equivalent (SE) were 52.9 ± 19.5 years (range: 10-91 years) and -1.81 ± 3.76D (range: -17.11-+8.72D). A strong correlation was found between age and ocular RMS HOA (r = 0.55, p < 0.001) and the age-related effect on spherical aberration (SA) was moderate (r = 0.30, p < 0.001). There was a moderate positive correlation between age and corneal RMS HOA (r = 0.46, p < 0.001), horizontal coma (r = 0.28, p < 0.001), and SA at 4-mm (r = 0.39, p < 0.001) and 6-mm (r = 0.55, p < 0.001) zones, indicating that these aberrations increase with age. Weak correlations were observed between SE and ocular SA at 4-mm (r = 0.27, p < 0.001) and 6-mm (r = 0.26, p < 0.001) zones, with SE explaining only a limited proportion of the observed variability. Gender-dependent differences were small but identified between ocular vertical trefoil (p < 0.01), corneal RMS HOA (p < 0.03), horizontal coma (p < 0.001), and oblique secondary astigmatism (p < 0.03). Conclusion: This large Caucasian cohort demonstrates the distribution of normative HOA data. Significant age, gender, and SE-dependent differences were identified that may be taken into consideration when mitigating HOA in clinical practice. Translational Relevance: Our data demonstrates the distribution and normative values of HOA among healthy phakic eyes and may serve as a reference for mitigation of wavefront errors in clinical practice.
