Correlation analysis of metabolic parameters influencing postoperative tendon healing after Achilles tendon rupture repair.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Postoperative healing quality critically determines functional recovery following Achilles tendon rupture (ATR) repair. Poor healing often leads to postoperative re-rupture. While mechanical factors influencing healing are well-studied, the role of metabolic disease remains unclear. Emerging evidence suggests metabolic disorders may impair tendon repair, yet their impact on early postoperative outcomes is underexplored. Purpose: This study hypothesized that metabolic disease (such as hyperuricemia and dyslipidemia) negatively affect early tendon healing after ATR repair. We aimed to identify key metabolic predictors of delayed healing to guide optimal management of perioperative metabolic parameters. Methods: Sixty patients with acute ATR undergoing surgical repair were included. Preoperative serum levels of uric acid (UA), triglycerides (TG), total cholesterol (TC), high-/low-density lipoprotein (HDL-C, LDL-C), and total bilirubin (TBIL) were measured. Postoperative signal-to-noise quotient (SNQ) values were calculated from T2-weighted MRI at 3 months. In preliminary analyses, Spearman's rank correlation and multivariate linear regression were conducted to assess associations between six metabolic biomarkers and SNQ, identifying significant metabolic markers. Subgroup analyses subsequently stratified patients into cohorts based on these determinants, with Mann-Whitney U test comparing intergroup SNQ differences. Results: Serum UA showed a significant positive correlation with SNQ ( Conclusion: Hyperuricemia is a significant metabolic factor impairing early ATR healing, highlighting the clinical utility of preoperative UA screening for personalized rehabilitation. Perioperative uric acid control is recommended for hyperuricemic patients to optimize Achilles tendon healing outcomes.
