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: Peritendinous adhesion as a common post-surgical complication usually occurs as a result of a large portion of sports and hard job-related injuries. This study aims to evaluate the repurposed potential of the immunosuppressive approved drug, tacrolimus, in decreasing adhesion band formation post-Achilles tendon surgeries in an animal model. Methods: Rats were randomly assigned to four groups control, sham with surgical intervention but no adhesion, positive control group with surgical transection and adhesion received no treatment, tacrolimus group was the same as the positive control group except that rats were treated with 2 mg/Kg/day tacrolimus orally for 21 days. The anti-inflammatory and fibrinolytic properties of oral tacrolimus treatment in attenuating the formation of adhesion bands were analyzed by One-way ANOVA or the Kruskal-Wallis test. Results: Tacrolimus decreased the length (P=0.001), density (P=0.001), grading (P=0.023), severity (P=0.001), and thickness (P=0.008) of post-surgical adhesion bands compared to the untreated group. Histopathological changes and recruitment of inflammatory cells to the tendon tissue sections were attenuated in the tacrolimus-treated group (P=0.001) in comparison with the positive control group. Compared to the untreated group, tacrolimus treatment decreased the expression of IL-1β (P=0.059) in the tendon tissue, but the difference was not statistically significant. Moreover, tacrolimus elicited anti-fibrotic responses by reducing the expression of tissue growth factor-β (TGF-β) in the tendon and inhibiting collagen deposition, fibrosis quantity (P=0.001), fibrosis grading (P=0.001), and total fibrosis scores (P=0.001), as visualized by Masson's trichrome staining. Conclusion: These results support the protective properties of tacrolimus in decreasing post-operative adhesion band formation in the animal model.
