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
ObjectiveHyperuricemia is a common metabolic disorder linked to systemic inflammation; however, its impact on perioperative hematological and inflammatory markers in patients residing in high-altitude regions who have undergone anterior cruciate ligament reconstruction remains unclear. We hypothesized that hyperuricemia is associated with a heightened perioperative inflammatory response.MethodsThis retrospective, cross-sectional study included 83 long-term high-altitude (≥2500 m) residents who underwent anterior cruciate ligament reconstruction between 2019 and 2025. Patients were divided into hyperuricemia (n = 40) and normouricemia (n = 43) groups based on their serum uric acid levels. Inclusion criteria included isolated anterior cruciate ligament injury, complete perioperative laboratory records, and confirmed preoperative hyperuricemia based on serum uric acid levels. Exclusion criteria included systemic inflammatory disease and incomplete data. Perioperative hematological and inflammatory parameters-including platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio-were compared using t-tests and chi-square tests.ResultsPreoperatively, the hyperuricemia group had lower neutrophil-to-lymphocyte ratio (1.17 ± 0.92 vs. 1.91 ± 0.82,
