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
aimTo investigate age-related differences in the iris-lens angle (ILA) among patients with age-related cortical cataracts and elucidate the impact of age on lens stability.
methodsA prospective observational study was conducted on patients with age-related cortical cataracts scheduled for phacoemulsification surgery. Preoperative ultrasound biomicroscopy (UBM) images were collected and analyzed. Initially, patients were stratified into two age groups: <60y and ≥60y, with no significant intergroup differences in sex or eye laterality. For further analysis, participants were subdivided into three age strata: <60y, 60-75y, and >75y. The ILA was measured in four quadrants (superior, inferior, nasal, and temporal). Intergroup differences in ILA were compared, and correlations between age and ILA parameters were analyzed using statistical methods.
resultsThe sample data were categorized into three groups according to age, <60y (113 patients; 55.8% female), 60-75y (245 patients; 61.0% female), and >75y (70 patients; 50.2% female). The superior quadrant ILA increased progressively with age stratification (
conclusionIn patients with age-related cortical cataracts, ILA increases with age, particularly in the superior and temporal quadrants, suggesting that advanced age is associated with greater lens deviation and decreased lens stability. UBM imaging can effectively evaluate the status of the zonule and lens stability, providing crucial evidence for personalized surgical planning based on patients' age.
