P values indicate differences between the hospitalized and the discharged patients. P < .05 was considered statistically significant. Means for continuous variables were compared using independent group t-test when the data were normally distributed; otherwise, the Mann-Whitney test was used. 1. The tests of B and NK cells were only performed for 34 inpatients and 7 discharged patients.
