The minimal groups' size, with and without TUS or CXR lung consolidation, was calculated according to the difference of the averages of neutrophil-to-lymphocyte ratio (NLR) in the reference the study of Yoon et al. Accepting alpha 0.01, for the probability of type 1 error, and power 80% for probability of type 2 error, a minimum sample size of 19 participants in each group (total 38) was required. Student's t-tests assessed the differences of CRP, WBC - white blood cells count - (TLC), neutrophil count (TNC) and NLR, between the groups with TUS and, separately, with CXR lung consolidation.Thereafter, by ROC (receiver operating curve) analysis, a cutoff of NLR, total leucocytes count (TLC), total Neutrophil count (TNC) and of CRP was calculated vs. the optimal reliability for the detection of TUS consolidation; sensitivity, specificity and accuracy (The proportion of all tests that are correct), and relative Odds Ratio (OR) and confidence intervals (CI) of the individual symptoms, and ORs of so defined laboratory assay cut-offs were calculated separately vs. TUS and CXR consolidation.
