Radiographic medial posterior tibial slope ≥16° predicts multiple revisions after anterior cruciate ligament reconstruction.

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: An increased posterior tibial slope (PTS) has been implicated as a risk factor for anterior cruciate ligament (ACL) graft failure. This matched case-control study aimed to compare radiographic and magnetic resonance imaging (MRI)-based PTS measurements between patients undergoing multiple revision anterior cruciate ligament reconstruction (ACLR) and those with successful primary ACLR and to identify thresholds predictive of high revision risk. Methods: In this matched case-control study, 156 patients were analysed: 78 patients undergoing multiple revision ACLR and 78 patients with successful primary ACLR. Medial PTS was measured on radiographs, while medial, lateral and PTS difference (PTS asymmetry) were measured on MRI. Group differences were assessed using independent Results: Radiographic medial PTS was significantly higher in the multiple-revision group (12.5 ± 3.5° vs. 11.2 ± 3.0°, Conclusion: Radiographic medial PTS showed the strongest differentiation between successful primary ACLR and multiple-revision ACLR. A PTS ≥ 16° identifies patients at significantly higher risk of multiple revisions, whereas MRI-based medial PTS, lateral PTS and PTS asymmetry provide no additional discriminatory value. Radiographic medial PTS appears practical for preoperative risk stratification, whereas MRI-based measures do not show similar utility. Level of Evidence: Level III.
