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

purposeThe aim of this study was to investigate gender-related differences in the sagittal curvature of the distal femoral condyle in the Korean osteoarthritic population

methodsThe sagittal curvatures of the distal femoral condyle of 1979 Korean patients (1680 female and 299 male) were evaluated using magnetic resonance imaging (MRI). MRI scans were obtained before total knee arthroplasty (TKA) in consecutive patients with end-stage osteoarthritis. The sagittal curvature of the distal medial and lateral femoral condyles was characterized with respect to the anterior, distal, and posterior circles. The diameter of each circle was measured. This study included 1873 varus and 106 valgus knees.

resultsThe anterior, distal, and posterior diameters were significantly greater in the male patients than in the female patients (P < 0.05). In the male patients, the lateral diameter was significantly greater than the medial diameter in the anterior and posterior circles (P < 0.05). However, in the female patients, the lateral diameter was significantly greater only in the anterior circle. In both genders, the medial diameter was significantly greater than the lateral diameter of the distal circle (P < 0.05). For both the varus and valgus knees, the lateral diameter was greater than the medial diameter in the anterior circle.

conclusionsIt has been concluded that the sagittal curvature of the femoral condyles in females is significantly different to their male counterparts. This study provides a reliable evaluation of the sagittal curvature of the femoral condyle in the Korean population. These gender-related differences in the sagittal curvature of the femoral condyle may require further investigation to determine surgical implications such as in TKA, and the existence of gender-related dimorphism in specific knee injuries and pathologies, such as ligament injuries and tibiofemoral problems. LEVEL OF EVIDENCE: III.
