Outcome measurements.
| Conductive thermal mattress group (n = 154) | Routine care group (n = 102) | P value | Relative risk (RR), 95% CI | Number needed to treat (NNT) | |
|---|---|---|---|---|---|
| Axillary temperature in the delivery room (labour room/operation theatre) ⁰C; mean (SD) | 36.3 (0.8) | 36.2 (0.6) | 0.28 | – | – |
| Axillary temperature in the NICU/postnatal ward ⁰C mean (SD) | 36.6 (0.6) | 36.4 (0.5) | 0.005 | – | – |
| Incidence of mild hypothermia ⁰C; n (%) | 18 (11.68) | 20 (19.60) | 1.00 | 0.59 (0.33,1.07) | 13 |
| Incidence of moderate hypothermia ⁰C; n (%) | 2 (1.29) | 6 (5.80) | 0.55 | 0.22 (0.04,1.07) | 22 |
Relative risk (RR): The ratio of the probability of neonatal hypothermia in the conductive thermal mattress group to the probability of neonatal hypothermia occurring in the routine care group.
Number needed to treat (NNT): The number of neonates that must be transported using conductive thermal mattress over a given period of time to prevent one adverse outcome (mild/moderate hypothermia).
