Between-individual effects (N = 3,945). The presented data include estimated regression coefficients (slope) with 95% CI. Headers show individual-level parameters, calculated as averages over the 14-day blocks for each individual. The regression coefficient shows that, for example, in comparison of two individuals with equal characteristics except one has on average one more missed basal insulin dose per 14 days, this individual would have a mean change in TIR of −2.76%.
