Fig. 6From: Identification of key ferroptosis-related biomarkers in steroid-induced osteonecrosis of the femoral head based on machine learningA The distribution of immune cell infiltration levels between disease and normal groups (*p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001). B Correlation diagram of differential immune cells (red sector represents negative correlation, blue sector represents positive correlation, and larger sector area represents greater absolute value of correlation coefficient). C Lollipop chart of correlation between 4 key ferroptosis-related genes and 20 differential immune cells (yellow to green indicates negative to positive correlation coefficients, the larger the circle is, the greater the absolute value of correlation coefficients, and the number in the back indicates the significance of p value)Back to article page
