“…Numerous studies involving several cohorts with a total of more than 900 pediatric patients on CSII [6, 7,10,11,12, 15,21,22,23,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41] reported a significant improvement in metabolic control, with a decrease of 0.5–1% in HbA 1c . However, when CSII was compared to MDI in randomized crossover trials in children [42] or adolescents [43] and in randomized controlled trials of short duration in diabetic toddlers and young children [5, 13], there was no significant difference in HbA 1c values.…”
