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: It has been demonstrated that exogenous testosterone can lead to higher rates of tendinous rupture and that injectable testosterone replacement therapy (TRT) is associated with more systemic complications. While this is the case, there are few studies exploring associations between injectable TRT and complications after anterior cruciate ligament reconstruction (ACLR) surgery. Purpose/Hypothesis: The purpose of this study is to evaluate the association between preoperative injectable TRT and ACLR revision surgery. It was hypothesize that ACLR revision surgery rates will be higher in patients undergoing TRT preoperatively compared with a matched cohort. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective cohort of patients who underwent ACLR between 2015 and 2022 was obtained through the PearlDiver Database (Mariner). Patients with a history of ACLR, 2 years of follow-up, and injectable TRT use before ACLR were identified using International Classification of Diseases, 10th Revision, and Current Procedural Terminology codes. Three TRT usage intervals were analyzed to evaluate ACLR revision rates in those with usage of injectable TRT compared with those with propensity score-matched demographics and Charlson Comorbidity Index with no history of injectable TRT use who underwent ACLR. Cohorts were via univariate analysis, chi-square tests, Student Results: TRT use ≤1 year before primary ACLR surgery demonstrated a 17.05% (66/387; mean age, 40.3) ACLR revision rate compared with 5.17% (20/387; mean age, 40.8) in the matched cohort control group ( Conclusion: Our study demonstrated that injectable TRT use within 1 year of primary ACLR is associated with a >3-fold increase in ACLR revision rates with 2 years of follow-up. Physicians should consider incorporating this increased risk into patient counseling during shared decision-making discussions, as this correlation may influence clinical and surgical decision making for patients with previous ACLR.
