Notes: Data are for total hospital stay. 1A conditional logistic regression method accounting for matched case-control data was used. The Mantel-Haeszel test was also applied for categorical data. The results from both methods were consistent. CPAP, continuous positive airway pressure; FIC, family integrated care; IQ, interquartile range; N/A, not applicable; SD, standard deviation; SNAPII, score of neonatal acute physiology version II.
