a
Firth penalized logistic regression models with profile-likelihood confidence intervals, adjusted for age ≥65, categorized Charlson score (0, 1, 2, ≥3), site, year, and time from illness onset to admission (in days).
b
2 RSV-negative/influenza-negative individuals were missing data on LOS.
c
Wald p-values.
d
Any mechanical ventilation (invasive or noninvasive). 1 RSV-negative/influenza-negative individual was missing information on mechanical ventilation status.
