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: Tibiofemoral rotational malalignment, recognized as a risk factor for recurrent patellar dislocation (RPD), has become a research focus. Although the relationship between femoral morphology and RPD is widely studied, the association between RPD and the tibial plateau and meniscus geometries related to the tibiofemoral rotation remains unexamined. Hypothesis: After accounting for the classic risk factors associated with knee rotation-tibial tuberosity-trochlear groove (TT-TG) distance and tibiofemoral angle (TFA)-targeted anatomical parameters are independently associated with adult RPD. Study Design: Cross-sectional study; Level of evidence, 3. Methods: This retrospective case-control study included 50 adult patients with RPD and 50 age-, sex-, and body mass index-matched controls. Knee magnetic resonance imaging scans were used to assess parameters-including the lateral tibial slope (LTS), medial tibial slope (MTS), lateral tibial height (LTH), medial tibial depth (MTD), medial meniscal bone angle (MMBA), MTS-LTS (slope difference), MTS: LTS ratio, MTS: MMBA ratio, TT-TG distance, and TFA. Differences among groups were compared; a multivariate logistic regression model was created to evaluate independent factors, and the diagnostic performance of the substantial risk factors, individually and in combination, was assessed. Results: The LTS ( Conclusion: The decreased LTS, increased LTH, decreased MMBA, increased MTS-LTS, and increased MTS: LTS ratio were associated with adult RPD. Importantly, even after controlling for TT-TG distance and TFA, increased LTH and decreased MMBA persisted as independent risk factors for adult RPD.
