Gain score comparison.

	Baseline; mean A1c; (SD)	Posttreatment; mean A1c; (SD)	A1c; t-value; (within subjects)	Gain score	Est. % below A1c 6.4 at baseline	Est. % below A1c 6.4 posttreatment	% t-value; (within subjects)	Impact Score
Control	8.70 (1.48)	8.18 (1.43)	−3.66**	−0.52	11.65%	14.53%	3.15**	2.88
Intervention	8.70 (1.47)	7.61 (1.34)	−8.29**	−1.09	12.73%	22.84%	6.96**	10.11
Significance; (between subjects)		𝑡(146) = 3.51,; 𝑃<0.01.		𝐹(1,146) = 7.25,; 𝑃<0.01				𝑡(146) = −4.20,; 𝑃<0.01.

Note. ^∗∗𝑃 < 0.01. % below A1c 6.4 is an estimate of the percentage of participants in each group who achieved an A1c level below 6.4. Gain Score is A1c change from baseline to posttreatment. Impact Score is the change in estimated percent below A1c 6.4 from baseline to post-intervention.
