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 examine the relationship between posterior tibial slope (PTS) and knee laxity before, during and after anterior cruciate ligament (ACL) reconstruction, using anterior tibial translation (ATT) measured as an arthrometer-based side-to-side difference and rotational laxity assessed during the pivot shift test via clinical grade and inertial sensor-based measurements of tibial acceleration and external rotational angular velocity (ERAV). Methods: This retrospective cohort study assessed patients who underwent primary ACL reconstruction with subsequent hardware removal. Medial PTS (MPTS), lateral PTS (LPTS) and slope asymmetry ( | MPTS-LPTS | ) were measured using magnetic resonance imaging. Based on a recent review, binary strata were defined as MPTS ≥ 9.05° versus <9.05° and LPTS ≥ 9.55° versus <9.55°, and comparisons were performed accordingly. Knee laxity was evaluated at three time points: preoperatively, at time-zero (intraoperatively during temporary graft fixation), and postoperatively (at the time of hardware removal), using ATT, pivot shift grade, acceleration and ERAV. Variables with Results: A total of 106 patients (24.3 ± 10.3 years; 37.7% male; 22.4 ± 2.7 kg/m Conclusion: Large MPTS was associated with increased postoperative rotational laxity, although no laxity was noted intraoperatively during temporary fixation. These results indicate that certain tibial slope morphologies may drive the onset of laxity. Preoperative assessment may help identify at-risk patients and optimize surgical strategy. Level of Evidence: Level IV.
