Barennes 2005	NI	NI	Blood glucose concentrations, collected through finger prick	Treatment failure rate, proportion of children not reaching a blood glucose concentration of ≥ 90 mg/dL during the study period. These data were used to determine 'resolution of hypoglycaemia within 80 minutes'. Early treatment failure rate: proportion of children with no blood glucose gain at 20 minutes.
