As regards the baseline clinical and laboratory data, there were no significant differences in the frequency percentage of fever, cough, dyspnea and anosmia, or the mean ± SD of the baseline CRP, serum ferritin, nutrophil/lymphocyte ratio and D-dimer , or the extent of CT chest infiltrates between azithromycin, clarithromycin or control groups, p > 0.05 for all (Table 1). This evidence concerns the gene CRP and Anosmia.
