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 describe the distribution of angle alpha orientation and magnitude in a large population and to analyze the impact of eye laterality, gender, and age on angle alpha. Setting: EENT Hospital of Fudan University and Shanghai Heping Eye Hospital, 2017-2023. Design: A retrospective analysis utilizing the iTrace system to examine preoperative angle alpha in patients undergoing cataract surgery. Methods: Angle alpha orientation and magnitude were collected from 30,705 individuals. The distribution of angle alpha direction and the value of its magnitude were analyzed. In addition, the influence of eye laterality, gender, and age on angle alpha was analyzed in different subgroups. Results: The analysis revealed that the binocular angle alpha orientation was predominantly located in the temporal region, followed by the nasal region, while the upper and lower regions had a smaller proportion. The average magnitude of angle alpha in the right eye was 0.32 ± 0.19 mm, larger than that of the left eye, and this result was consistent in all subsequent subgroup studies. In a subgroup analysis categorized by gender, females exhibited significantly larger angle alpha than males. Furthermore, in an age-grouped subgroup analysis, a clear tendency was observed that the angle alpha value was increasing with age. Conclusion: This study analyzed the distribution of angle alpha in a large population and is the first to report the effects of eye laterality, gender, and age on angle alpha. These findings enhance ophthalmologists' understanding of angle alpha and provide a deeper perspective for cataract surgical planning.
