| ECFC Characteristics | Term (N) | Preterm (N) | P Value | ||
|---|---|---|---|---|---|
| Time to first ECFC colony formation, days, median (IQR) | 34 | 12 (11–16) | 32 | 15 (12–19) | 0.028a |
| Proliferation rate, % of total cells, median (IQR) | 31 | 27 (17–35) | 31 | 20 (15–27) | 0.042a |
| Closed tubes formed, n per 1.5×104 ECFC, median (IQR) | 31 | 8 (1–15) | 31 | 5 (1–10) | 0.126 |
| Branches formed, n per 1.5×104 ECFC, median (IQR) | 31 | 32 (16–38) | 31 | 25 (14–35) | 0.310 |
Data assessed by independent samples Mann–Whitney U test. ECFC indicates endothelial colony‐forming cells; IQR, interquartile range.
