Multiple linear regression analysis for testing the influence of variables on changes in DTSQ treatment satisfaction score

Explanatory variable	Parameter estimates	95% CI	P value	Adjusted R2
HbA1c changes: Baseline to 36 months	−0.698	−1.074, −0.323	0.0003	0.3231
Baseline DTSQ treatment satisfaction score	−0.569	−0.617, −0.522	< 0.0001
Baseline HbA1c	−0.376	−0.742, −0.011	0.0437

Explanatory variables were continuous values and the association was estimated per 1% increment in HbA1c and per 1 point increment in DTSQ treatment satisfaction score. A P value < 0.05 was considered significant.
