N-chlorotaurine does not alter structural tendon properties: a comparative biomechanical study.
Article in Archives of orthopaedic and trauma surgery, 2025. 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
introductionN-chlorotaurine (NCT) is a well-tolerated antiseptic with broad-spectrum microbicidal activity and could therefore be a promising alternative to vancomycin, the current standard of care for the prevention of postoperative septic arthritis (PSA) after anterior cruciate ligament reconstruction (ACLR). MATERIALS AND
methodsThe aim of this study was to evaluate whether soaking bovine extensor tendons in N-chlorotaurine (NCT), vancomycin, or 0.9% saline influences structural tendon properties. In this controlled biomechanical study, fifty bovine extensor tendons were randomized into groups and soaked for 10 min in distilled water solutions containing either 1% vancomycin, 1% NCT, 5% NCT, 5% NCT with 0.1% ammonium chloride, or 0.9% saline. Tendons were then mounted in cryo-clamps and subjected to uniaxial tensile testing until failure. Failure mode, ultimate load, ultimate elongation, and stiffness of the linear region from the load-elongation curve were extracted and compared for each graft.
resultsNo statistically significant differences were detected across all measured parameters (p > 0.05) and solutions. The mean ultimate load, ultimate elongation, stiffness and elastic modulus were not statistically significantly different between all five tested solutions.
conclusionsBoth NCT and vancomycin even at high concentrations do not impair structural tendon properties compared to 0.9% saline. NCT appears to be safe for clinical use from a biomechanical perspective.
