  1. aData are presented as mean (SD) unless indicated otherwise. Percentages reported are for caregivers with data available for each specific variable. Missing data (overall) were n = 1 for all variables, except medical conditions and diabetes drug use (no missing data)
  2. bDiabetes status was unknown for one caregiver, thus N = 1494
  3. cThe Case Report Form collected only birth year data, thus the missing month and day were imputed with 15 July. Age is the year part of the difference between the date of Informed Consent and the imputed birth date
  4. dData include the presence of diabetes
  5. P-values are for the comparison between caregiver diabetes groups (ANOVA for continuous variables, with country and diabetes status as factors, and Cochran–Mantel–Haenszel test for categorical variables, with stratification by country)
  6. P-values indicating statistically significant differences between caregiver diabetes groups (p < 0.05) are highlighted in bold type
