The significant (P < .1) findings from each model following backward elimination are shown. RR indicates rate ratio; CI, confidence interval; OR, odds ratio.
a
Reference group is children without NI.
b
Includes the use of MV, CPAP, or BiPAP during hospitalization.
c
Sometimes home includes children alternating between home and a postacute care facility across multiple hospital discharges.
