Relationship between body weight measurements obtained in weight loss study and routine clinical care at 6 and 12 months.

	Month 6 study completers (n = 238)	Month 12 study completers (n = 224)
EMR* weight available, n (%)	143 (60%)	142 (63%)
Study vs. EMR weight
Study weight, kg:† mean (s.d.) ‡	100.9 (18.2)	101.3 (19.7)
EMR weight, kg: mean (s.d.)	101.0 (18.3)	101.2 (19.5)
Difference, kg: mean (s.d.)	−0.2 (4.8)	0.1 (2.4)
Correlation	0.96	0.99
