Table 2.

Effect of the TXT2BFiT program on measured weight and BMI outcomes for all randomized participants in the study by allocation (intention-to-treat analysis) (n=250).

Measured variable	Intervention group (n=125)^a, mean (SD)		Control group (n=125), mean (SD)		Model β^b (95% CI)	P
	Baseline	12 weeks	Baseline	12 weeks
Body weight, measured in kg	78.3 (11.4)	76.4 (11.1)	79.3 (12.7)	79.5 (12.4)	2.2 (0.8-3.6)	.005
BMI^c, measured in kg/m²	27.3 (2.4)	26.4 (1.9)	27.1 (2.7)	26.8 (2.2)	0.5 (0.1-1.0)	.02

^aAll participants had measured variables including 2 participants who did not complete baseline self-report surveys.

^bModel coefficients and P values were obtained from analysis of covariance models adjusting for baseline values, general practitioner clinic, and gender. Missing baseline and follow-up values were imputed to create five datasets and results were pooled using Rubin’s rules.

^cBody mass index (BMI).
