Efficacy
Statistical methods / analysis
This pilot study will recruit 20 participants. This will afford adequate statistical power to assess the primary outcome, and will also inform the feasibility of recruiting and carrying out a larger, study with adequate power to detect clinically meaningful differences in the secondary outcomes.
Assuming alpha of 0.05 and beta of 0.1, detecting a reduction in maternal hyperglycaemia requiring an increase in insulin dose from 90% in the maternal administration group to 30% in the fetal administration group, would require a total sample size of 18 participants.
Statistical analysis will be by intention to treat and, if appropriate, by treatment received. Maternal and fetal/neonatal characteristics will be assessed with descriptive statistics and compared with appropriate parametric or non-parametric tests for normal and skewed distributions, respectively. The proportional rates of the primary and secondary outcomes will be compared with Chi-squared tests. Continuous outcomes will be assessed with t-tests. A p-value of <0.05 will be considered significant. For outcomes with multiple comparisons, the Bonferroni correction will be applied to account for multiple testing. In this pilot study there will be no planned interim analysis.
