Analysis of density histogram curves (a) and correlation between HU and TSS (b) in COVID-19 patients (N = 27) at hospital admission and follow-up. ***p < 0.001 between groups (compared via two-way ANOVA). Data in (a) are reported as mean and 95%CI. CI confidence interval, COVID-19 coronavirus disease 2019, HU Hounsfield Units, RF relative frequency, TSS total severity score
