System Setting Ratios (Actual/Calculated) and Percentage Time-in-Range

Variable	Mean (SD)	Min	Max
Basal ratio	1.09 (0.272)	0.58	1.62
ISF ratio	1.25 (0.528)	0.03	2.23
CIR	1.07 (0.325)	0.62	1.73
TIR (%)	75.74 (16.638)	33.83	97.03

n = 22 for discontinuer subsample with system settings data. Ratios compare actual setting divided by calculated (optimal) setting, with values closer to 1 reflecting more congruency between actual and calculated settings.

CIR, carbohydrate-to-insulin ratio; ISF, insulin sensitivity factor; SD, standard deviation.
