Mean EQ VAS scores in individuals with diabetes compared to control individuals by disease duration. ANOVA and post hoc tests showed significant differences between the cohorts of men with diabetes (p = 0.004) which were found between the 1983 cohort and the 2008 (p = 0.020) and 1999 (p = 0.028) cohorts. Between the cohorts of male control individuals significant differences were found (p < 0.001) between the 1983 cohort and all other cohorts (1992, p = 0.045; 1999, p = 0.040; 2008, p < 0.001). The post hoc tests could not detect any significant differences between the cohorts for women, neither for women with diabetes nor for the control individuals.
