All data analysis was performed using ANOVA (mean ± sd), except for apgar scores and days of mechanical ventilation, which analyzed using median test. *Defined as feeds being held for more than 24 hours, while on study. †Confirmed by echocardiogram. ‡Defined as when TPN was discontinued. §Excluding azithromycin. ¥Performed using wilcoxon rank sum test.
