| Values are n (%). | ||||
| *Hourly respiration recordings were required for all women receiving magnesium sulphate. In the non-Magpie group 65 women received magnesium sulphate and required hourly respiration recording. All women in the Magpie trial could potentially have received magnesium sulphate and therefore required hourly respiration monitoring. | ||||
| Bonferroni correction applied to account for multiple testing and the increased probability of chance findings achieving significance. | ||||
