The correlation between immune-inflammatory parameters and cardiac injury. Spearman’s correlation of the contribution of immune-inflammatory response to cardiac injury is analyzed in all COVID-19 patients (A), non-DM patients (B), and DM patients (C). The color and number key represent the significant regression coefficients of the variables, while the blank means no statistical difference.
