  • 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.

  • d Reference group is children aged 13 to 18 years old.
