Results are presented as median (IQR). P values compare each group, hospitalized and nonhospitalized, vs their own baseline. Bold P values indicate statistically significant results (P < .05).
ALT, alanine transaminase; NA, not available.
Calculated as follows: NLR = (absolute neutrophil count)/(absolute lymphocyte count).
