a
Figures are No. (%) unless stated otherwise. If indicates denominators for testing of fewer cases than full group, will be listed. Fisher's exact test was used to compare categorical variables. NA, not applicable. PNEU, pneumonia.
b
Data on pneumonia diagnosis during hospitalization not collected.
c
The p-values represent the differences of distribution among the time points of follow-up.
d
The p-values represent the differences of distribution between pneumonia and non-pneumonia patients in a time point of follow-up.
