Fig. 3From: Clinicopathological classification of immune checkpoint inhibitor-associated myocarditis: possible refinement by measuring macrophage abundanceCorrelation of cardiac biomarkers and macrophage cell counts. A Cardiac troponin I and B N-terminal pro-brain natriuretic peptide (NT-pro BNP) levels plotted against corresponding CD68 positive macrophage cells counts per high powered field (HPF). Data were compared using Spearman correlation coefficient analysis with values of P < 0.05 being considered statistically significantBack to article page
