| Intervals between measurements | Groups | ||
|---|---|---|---|
PT-KAN ( ±SD) | PT-NKAN ( ±SD) | T ( ±SD) | |
| 0 h | 31.85±6.93 | 37.59±4.42 | – |
| 48 h | 49.30±4.91 | 38.17±3.10 | – |

Analysis of variance for repeated measurements: F(5,108)=56.69; p<0.001. Multiple comparisons (Holm-Sidak test): in the PT-KAN group: 0 h×48 h (p=0.004), 0 h×TEA (p=0.004). Between the PT-KAN and T groups: TEA×TA (p=0.004).
-
PT-KAN, preterm newborns in the kangaroo position; PT-NKAN, preterm newborns not in the kangaroo position; RMS, Root Mean Square; SD, standard deviation; T, term newborns; TA, term age (for T group); TEA, term equivalent age (for the PT-KAN group).
