Univariate analysis: All factors with P < .20 were entered into the multivariate model. Multivariate analysis: Only factors with P < .05 are shown. Multivariate analysis was adjusted for the covariates prematurity and age, which were found to be significant in univariate analysis and subsequently in multivariate analysis using the manual forward stepwise procedure. Secondary outcome was missing for 31 RSV–infected children.
Abbreviations: ADV, adenovirus; aOR, adjusted odds ratio; CI, confidence interval; EV, enterovirus; HMPV, human metapneumovirus; ICU, intensive care unit; LOS, hospital length of stay; MV, mechanical ventilation, OR, odds ratio; PIV, parainfluenza virus; RV, rhinovirus, RSV: respiratory syncitial virus.
Any viral respiratory coinfection with HMPV, RV, ADV, EV, influenza, PIV1, PIV2, or PIV3.
