Association between Osteopenia and days of supplemental feeding among preterm infants (n = 26).

Variable	No Osteopenia (n = 13) Median* (range)	Osteopenia (n = 13) Median* (range)	p-value**
Days of NPO	6 (2–19)	11 (6–24)	0.03
Days to full feeding (120 ml/kg/day)	32 (22–39)	27 (11–41)	0.54
Days of PN intake	27 (13–42)	32 (22–42)	0.31

^*Median of the variables in the first 6 weeks of life. PN = parenteral nutrition.

^**P-values based on the Wilcoxon Rank sum test. Significant at p < 0.05.
