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
Purpose: To report the safety and efficacy of biointegrative fiber-reinforced implants for tibial tubercle osteotomy (TTO) and perform a cost-benefit analysis. Methods: Patients treated with TTO for all indications by a single surgeon from May 2017 to July 2024 were retrospectively reviewed. There were no exclusion criteria. In 2023, the surgeon switched TTO fixation from two 4.5-mm metal compression screws to 2 biointegrative, partially threaded 4.0-mm headless compression screws, made of continuous mineral fibers comprised of elements found in natural bone (SiO Results: Sixty-two TTOs were analyzed (44 metal, 18 biointegrative); 61.3% of patients were female, and the median age was 23.3 years (interquartile range 22.5). One patient with biointegrative implants underwent irrigation and debridement with implant retention at 9 days postoperatively. Mean follow-up for biointegrative fixation was 1.3 ± 0.4 years (range: 0.5-1.8) and for metal fixation was 3.5 ± 1.8 years (range: 0.4-6.7), Conclusions: Biointegrative screws are a safe and effective alternative to metal screws for TTO in short-term follow-up. The use of biointegrative fixation may reduce the need for secondary hardware removal procedures commonly reported with 4.5-mm metal screws, albeit at a potentially increased cost to the health system. Level of Evidence: Level III, retrospective comparative study.
