1 · What the graph read from it

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.

2 · The registry

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 investigate factors that affect return to physical activities after open wedge high tibial osteotomy (OWHTO), and to determine whether an optimal correction angle exists for return to physical activities. Methods: Patients with medial osteoarthritis of the knee who underwent OWHTO at our institution were evaluated. Radiographic evaluations were performed using bilateral weight bearing long leg radiographs. The clinical evaluation consisted of the Tegner activity scale, the Knee Injury and Osteoarthritis Outcome Score (KOOS) Sports/Rec subscore, and the presence of residual flexion contracture of 10° or more in unstable hinge fractures. In addition, the degree of cartilage damage in the medial compartment was evaluated via arthroscopic surgical findings according to the ICRS classification. Results: Sixty patients (70 knees; 25 males and 45 females; mean age, 55.2 [32-75] years; mean follow-up, 8.5 [3.8-12.4] years) were included in the study. The preoperative alignment defined by mean WBLR (%) was significantly higher in the Return to High Physical Activity Group (H Group: 31.0 ± 18.6) than the Return to Low Physical Activity Group (L Group: 15.9 ± 13.9). Logistic analysis showed that low preoperative WBLR and the absence of severe cartilage damage to the medial compartment, postoperative flexion contracture, and unstable hinge fracture were factors affecting return to sport. In addition, the cutoff values using the Youden Index based on ROC analysis were preoperative Tegner activity score of 4.0 and preoperative KOOS (Sports/Rec) of 35.0. Conclusion: Preoperative KOOS (Sports/Rec) was a useful index for predicting postoperative return to high physical activities. Depending on the degree of arthroscopic cartilage damage, the under-collection of cases with severe cartilage damage should be avoided. Level of Evidence: Level IV, retrospective case series.
