TABLE 3.

Changes in body weight and BMI measures between baseline and 6‐month follow‐up.

Body weight and BMI measures	N	Mean baseline measure ± SD	Mean 6‐month follow‐up measure ± SD	Mean change ± SD (baseline to 6‐month follow‐up measure)	95% CI	p‐value a
Body weight (kg)	343	106.8 ± 20.7	96.3 ± 21.0	−10.5 ± 6.8	−11.2; −9.8	<0.001
BMI (kg/m2) b	321 c	37.9 ± 5.5	34.4 ± 6.2	−3.7 ± 2.4 d	−4.0; −3.4	<0.001

Note: The bold signifies the difference between the mean baseline measure and the mean 6‐month follow‐up measure.

Abbreviations: BMI, body mass index; CI, confidence interval.

^a Statistical significance of change from baseline to the 6‐month follow‐up.

^b Change in BMI was not calculated for patients with baseline and follow‐up BMI measures of 45 or greater.

^c BMI at baseline, N = 343.

^d Mean change in BMI does not equal to 3.7 kg/m² because the change was calculated for only 321 out of 343 patients.
