Fig. 6From: Identifying hub genes and immune infiltration of osteoarthritis using comprehensive bioinformatics analysisImmune infiltration analysis performed in OA tissues. Barplot (A) and heatmap (B) showed the composition of 22 subpopulations of immune cells in 36 OA synovial and 29 normal controls. C Heatmap showed the correlation between 22 kinds of immune cells in OA and numeric in each tiny box indicating the p value of correlation between two types of cells. D The violin plot showed the difference of immune infiltration between OA (red color) and normal controls (blue color)Back to article page
