  • Data are means ± SD or proportion, number in each group, and significant differences. A1C in 2001 and 2006 in the analysis of age-groups is adjusted for sex. ANOVA shows that glycemic control was worse in children aged >10 years compared with children 5–9 years (P < 0.001) and compared with children aged <5 (P < 0.001). A1C of patients where a new PDSN had been appointed is adjusted for age and sex. A center versus time interaction (P < 0.001) indicates that glycemic control improved in centers that appointed a new PDSN compared with centers that did not.
