  1. Panel A: whole study population (n = 60); Panel B: No-Steroids group (n = 17); Panel C: Steroids group (n = 43). Each HU compartment was reported as absolute values as well as percentage of the total lung parenchyma. Data were reported as mean ± standard deviation (SD). Wilcoxon rank-sum test was used to detect statistical differences (α = 0.05); *: to mark statistically significant differences
