Fig. 3From: Correlation between lung infection severity and clinical laboratory indicators in patients with COVID-19: a cross-sectional study based on machine learningCorrelation between total pulmonary POI and L%, LY count, or N%. POI of the total lung was negatively correlated with the L% [r = −0.633, P < 0.001, (a)] and LY count [r = − 0.555, P = 0.001, (b)] but positively correlated with the N% [r = 0.565, P = 0.001, (c)]Back to article page
