INS and type 1 diabetes mellitus: This effect is related to: (1) the glucose patterns heterogeneity among subjects (i.e., inter-subject variability) (49), specially in people with T1D (50); (2) the day-to-day CGM variability (i.e., intra-subject variability) (51); and (3) the various factors that influence the subject's glucose dynamics (such as insulin administration, subject metabolism, carbohydrate intake, physical activity) that are not contemplated in the proposed DL models training because only CGM data were employed in this study.
