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

backgroundBicruciate-retaining (BCR) prostheses have been introduced to recreate normal knee movements by preserving both the anterior and posterior cruciate ligaments. One of the surgical procedures essential to the success of BCR total knee arthroplasty (TKA) is preservation of the tibial eminence. However, in our clinical experience, we found that a well-preserved tibial eminence changed its shape chronologically after the operation. This study aimed to investigate the frequency of chronological changes in the tibial eminence after BCR TKA and its influence on the outcomes.

methodsThis study included 59 patients with BCR TKA. Radiographs taken at 2 weeks postoperatively and at an average follow-up of 3.2 years were used to assess the tibial eminence. The patients' demographics, joint component gaps, and clinical scores were compared between the groups with chronological change (P group) and without change (N group).

resultsThe chronological change of the tibial eminence was found in 22 cases (37%). The joint component gaps at extension were larger in P group than in N group. The scores in the symptoms and ADL subscales of the KOOS were significantly higher at 1 year postoperatively in N group than in P group. There were no significant differences between the two groups at the final follow-up.

conclusionsChronological changes in the well-preserved tibial eminence were found in approximately one third of the BCR TKA patients. The mean scores at 1-year postoperatively were lower in the patients with chronological changes in the tibial eminence than in the patients without changes.
