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

backgroundAlthough Baker's cysts are commonly associated with meniscal tears, the role of specific tear morphologies and anatomic locations in cyst presence remains unclear. This study aimed to evaluate the associations between meniscal tear patterns, tear locations, and Baker's cysts and to explore whether these tear characteristics were also associated with concomitant chondral lesions.

methodsIn this retrospective cohort study, patients who underwent knee arthroscopy at a single institution were evaluated and categorized according to the presence or absence of a Baker's cyst on MRI. Arthroscopic video recordings were reviewed to identify meniscal tear morphology and tear location based on the Cooper classification, as well as the presence of chondral lesions. Separate multivariate logistic regression models were constructed for tear morphology and tear location to account for collinearity among meniscal variables.

resultsOf 353 patients (mean age 35.5 ± 13.4 years), 77 (21.8%) had a Baker's cyst. In the multivariate tear morphology model, horizontal, radial, and complex medial meniscal tears were significantly associated with Baker's cysts (OR: 7.321, 95% CI: 2.921-18.349, p < 0.001; OR: 3.380, 95% CI: 1.136-10.056, p = 0.039; and OR: 4.000, 95% CI: 1.907-8.394, p < 0.001, respectively). In the multivariate location model, tears involving Cooper zones A2, A3, and B3 were also significantly associated with Baker's cysts (OR: 2.956, 95% CI: 1.133-7.713, p = 0.027; OR: 3.978, 95% CI: 1.838-8.606, p < 0.001; and OR: 7.070, 95% CI: 2.878-17.371, p < 0.001, respectively). Chondral lesions remained independently associated with Baker's cysts in both models. In univariate analyses, these tear types and locations were also associated with chondral lesions, although these associations were not maintained after multivariate adjustment.

conclusionIn this retrospective cohort, horizontal, radial, and complex medial meniscal tears, particularly those involving Cooper zones A2, A3, and B3, were associated with the presence of Baker's cysts. These findings expand the current literature by providing a more detailed description of the relationship between meniscal tear morphology, tear location, and Baker's cysts, and may serve as a basis for future studies investigating the underlying mechanisms.
