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

backgroundPosterior cruciate ligament (PCL) injury is common in sports, with anatomical factors like posterior tibial slope (PTS) and femoral intercondylar notch morphology potentially influencing risk. However, evidence remains limited and inconsistent. In addition to the PTS and femoral intercondylar angle, this study also investigated the potential roles of the lateral proximal tibial angle and lateral distal femoral angle in posterior cruciate ligament injuries.

methodsA retrospective study was conducted including 169 participants: 80 with isolated PCL injuries and 89 controls. Anatomical parameters (PTS, femoral intercondylar angle, etc.) were measured from imaging. Univariate and multivariate analyses were used to evaluate associations with PCL injury.

resultsNo significant differences in demographic variables. The PTS was significantly lower in the PCL group (7.81° ± 3.59°) than controls (11.06° ± 4.07°, P < 0.001). The femoral intercondylar angle was also smaller in cases (P < 0.05). Other parameters showed no significant differences. ROC analysis indicated that lower PTS and narrower intercondylar angle were associated with higher PCL injury risk.

conclusionPTS ≤ 6.5° and an intercondylar angle ≤ 49.5° were associated with a significantly increased risk of PCL injury.
