ac Logarithmic scatter plots show significant correlation for the mean amount of calcified cartilage (CC) in percentage of total cartilage area between the left and right acetabular labrum (r = 0.70, 95% CI 0.57 0.79), p < 0.001) (a), the medial meniscus and the acetabular labrum (r = 0.66, 95% CI 0.52 0.76), p < 0.001) (b) and the femoral head and the acetabular labrum (r = 0.48, 95% CI 0.30 0.63), p < 0.001) (c). Data points are jittered to avoid over plotting. Logarithmic scatter plots are shown with the blue orthogonal regression line and with the corresponding correlation coefficient (r). d Logarithmic effect plot of the mean amount of CC in percentage of total cartilage area for the femoral head, the acetabular labrum and the medial meniscus. The amount of CC in the fibrocartilage of the acetabular labrum was significant larger compared to the amount of CC in the medial meniscus (factor of 1.3, p < 0.001) and the amount of CC in the acetabular labrum was significant larger compared to the amount of CC in the hyaline cartilage of the femoral head (factor of 3.0, p < 0.001)
