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
Background: Pterygium is a prevalent ocular surface disorder globally. Postoperative recurrence poses a significant challenge to clinical management. Current evidence regarding recurrence risk factors is predominantly derived from urban populations. This study aimed to investigate the specific risk factors for pterygium recurrence within a remote population in Southern China. Methods: This retrospective, institution-based case series analyzed 200 patients who underwent primary pterygium excision combined with limbal-conjunctival autograft between January 2016 and February 2022. Patients were stratified into recurrent and non-recurrent groups based on postoperative outcomes. Cumulative recurrence rates were estimated using Kaplan-Meier survival analysis. Multivariate binary logistic regression was performed to identify independent risk factors for recurrence. Results: The mean time to recurrence was 42.21 ± 22.13 months, with a median recurrence-free survival of 72.0 months. Compared to the non-recurrent group, patients in the recurrent group were significantly older (67.62 ± 5.79 vs. 60.27 ± 10.33 years, Conclusion: In rural southern China, pterygium recurrence is distinguished by a delayed onset pattern. Our findings highlight advanced age as a robust independent risk factor in this region, necessitating a shift in clinical focus. Management strategies in underserved areas should prioritize elderly patients through extended follow-up periods and targeted health education to mitigate recurrence risks.
