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 assess femoral and tibial tunnel positioning after primary hamstring autograft anterior cruciate ligament (ACL) reconstruction using postoperative three-dimensional computed tomography (3D-CT), and to evaluate whether tunnel placement differs with the use of a 7-mm femoral offset aimer and surgeon experience. Methods: This retrospective cross-sectional study included patients aged 18-50 years who underwent Primary single-bundle hamstring ACL reconstruction between 2022 and 2025 and had postoperative 3D-CT imaging available. The femoral and tibial tunnel positions were assessed using validated 3D-CT measurement methods and then classified according to the published anatomic reference ranges. The association of tunnel accuracy with 7-mm femoral offset aimer use and surgeon experience was analysed. Interobserver reliability was assessed using the intraclass correlation coefficient. Results: Eighty-six patients were included (37.2% female; median age 25.5 years). High-experience surgeons performed the procedures in 39.5% of cases, and a 7-mm offset aimer was used in 81.4% ( Conclusion: In this retrospective 3D-CT study, 7-mm femoral offset aimer use was associated with a more posterior femoral tunnel position but not with improved overall anatomic accuracy. Surgeon experience was not associated with femoral or tibial tunnel accuracy. The clinical relevance of these radiological findings remains uncertain. Level of Evidence: Level III.
