Immune infiltration analysis (A) Panorama of infiltration of 22 types of immune cells between high and low OA Pyroptosis score groups. (B) Differences of each type of immune cells and immune function between high and Low-Pyroptosis score groups (*p < 0.05; **p < 0.01; ***p < 0.001). (C) Correlation heatmap between immune cells. (D) Correlation heatmap between immune cells and hub genes. Red color represents positive correlation, purple color represents negative correlation, and the intensity of the color indicates the degree of correlation.
