The profiles of CSII and non-CSII users differed: CSII users were significantly older (mean age 22.9 versus 21.5 years; t = 5.011, p < 0.001); had diabetes longer (mean 11.2 versus 9.8 years; t = 2.886, p < 0.004); received more planned service contacts/two years (mean 11.5 versus 6.25 contacts; t = 6.535, p < 0.001); more HbA1c measurements/ two years (mean 4.2 versus 2.6 measurements; t = 6.353, p < 0.001); more BP measurements/two years (mean 2.6 versus 1.5 measurements; t = 5.523, p < 0.001); and more ACR measurements/two years (mean 1.0 versus 0.7 measurements; t = 3.291, p < 0.002). The gene discussed is ACR; the disease is diabetes mellitus.
