Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomised cross-over trial of 3 treatment doses of glucose for hypoglycaemia (0.2 g/kg, 0.3 g/kg and 15 g).

As per protocol each treatment is administered as glucose tablets at onset of spontaneously occurring hypoglycaemia, and only repeated at 10 minutes if hypoglycaemia has not resolved. As blood glucose is very dynamic "a wash-out" is not really applicable, and hypoglycaemia had always resolved prior to any repeat episodes. Patients record on the treatment sheet when an episode occurs, what treatment is given and then blood glucose at specified intervals - it si unlikely they would complete the data sheet without adhering to treatment for that episode.

Comparator / control treatment
Randomised cross-over trial of 3 treatment doses of glucose for hypoglycaemia (0.2 g/kg, 0.3 g/kg and 15 g). 15 g is current standard treatment, 0.2 and 0.3 g/kg are comparator treatments

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects recruited from diabetes clinic. One of three treatments randomly allocated by sealed envelope for each episode requiring treatment (up to 15 per subject)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Details of treatment dose and recording sheet written on each treatment episode form, placed in sealed envelope and then shuffled. for each subject, 5 envelopes for each treatment (15 envelopes altogether) provided. Envelopes then shuffled and numbered from 1 to 15, with subjects instructed to take the next numbered treatment episode envelope. This is simple randomisation, akin to dice-rolling. No stratification required.
Masking / blinding
