| Postnatal age (days) | Tc mean (°C) | Tc SD | Tp mean (°C) | Tp SD | Td mean (°C) | Td SD |
|---|---|---|---|---|---|---|
| 1 | 36.8 | .56 | 36.5 | .57 | 0.4 | .51 |
| 2 | 37.1 | .43 | 36.4 | .52 | 0.8 | .46 |
| 3 | 37.2 | .38 | 36.3 | .61 | 0.9 | .56 |
| 4 | 37.2 | .44 | 36.2 | .58 | 1.0 | .58 |
| 5 | 37.2 | .38 | 36.1 | .64 | 1.0 | .60 |
Tc: (day 1 vs day 2)and (day 1 vs day 5) −P < 0.0001. Td: (day 1 vs day 2) and (day 2vs day 5)−P < 0.0001. Tp: (day 1 vs day 5) −P = 0.001.
