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

Background: Bone morphology is a well-recognized risk factor for primary and secondary anterior cruciate ligament (ACL) injury. Purpose: To evaluate lower-extremity bone morphology using computed tomography (CT) in patients after primary ACL reconstruction and investigate the association between the risk of ipsilateral graft rupture and contralateral ACL injury. Study Design: Case-control study; Level of evidence, 3. Methods: This study included 224 consecutive patients who underwent primary ACL reconstruction at our hospital. Postoperative CT scans obtained within 1 week were used to determine the following morphological parameters: femoral neck anteversion, medial and lateral posterior tibial slope (PTS), femoral notch width, notch width index, medial tibial spinal height (MTSH), lateral tibial spinal height, and tibial torsion. These bony morphological parameters were compared between patients with and without graft rupture and between those with and without contralateral injury. Multivariate logistic regression was performed to identify independent risk factors for graft failure and contralateral ACL injury. Results: Graft rupture occurred in 16 patients (7.1%), and contralateral ACL injuries occurred in 22 patients (9.8%). Patients with graft rupture had smaller MTSH than those without graft rupture ( Conclusion: In patients who underwent primary ACL reconstruction, a smaller MTSH was associated with a higher risk of graft rupture, whereas a greater tibial torsion was associated with a higher risk of contralateral ACL injury.
