Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Children have the settings controlling their insulin infusion pumps adjusted by a credentially diabetes educator using recommendations from PumpTune computer algorithm once and then are monitored with continuous glucose monitoring for a further six days. There was no washout period separating these six days from the comparison period.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
In this cross over trial the order the interventions were applied was randomised. An independant person used a randomisation table to allocate the order. Each set of pump adjustment instructions was placed into a sealed opaque envelope. The number 1 was written on the outside of the instructions to be used first and number 2 for those to be used second. The diabetes educator who entered the adjustments into the pumps was blinded as to the origin of the instructions.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randmisation table based on permuted blocks was generated by a statistician using software package Stata v 13.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
