Notes: For n = 195 subjects after excluding subjects who have missing values in any variables. Abbreviations: MDI, multiple daily injections; ADI, area deprivation index Unadjusted model is adjusted by hour and hour². Fully adjusted model includes all predictors. Parsimonious model includes only predictors which are significant or in the fully adjusted model significant at the p<0.05 level Significant at the level Significant at the level.
