Table 2 Key clinical outcome variables at baseline and six months

		Baseline	6 months	mean difference
		mean (min., max.)	mean (min., max.)	(95 % CI)
Variables assessed from medical chart audit
	HbA1c (%)	8.0 % (6.0 %, 12.6 %)	7.6 % (5.9 %, 11.6 %)	-0.5 % (-1.0 %, -0.0 %)*
	Body Mass Index (BMI)†	39.8 (29.5, 63.9)	40.0 (31.2, 66.8)	0.1 (-0.7, 0.9)
	Blood pressure systolic (mmHg)	134.0 (101, 194)	121.7 (91, 172)	-13.0 (-18.9, -7.1)**
	Blood pressure diastolic (mmHg)	77.2 (56, 97)	74.0 (57,100)	-3.3 (-7.6, 1.0)
		n/N (%)	n/N (%)	OR (95 % CI)
Variables assessed during Home Assessments
	Depression^a	21/34 (62 %)	12/31 (39 %)	0.4 (0.2, 0.9)***
	Self-rated health status^b	11/32 (34 %)	16/31 (52 %)	2.0 (0.8, 5.2)

Note: * p = 0.05, ** p < 0.001; *** p = 0.03† only n = 14 patients had both baseline and 6 months BMI values recorded and reported here; ^aDepression assessed using adapted PHQ-9 – dichotomised as moderate to severe depression vs. otherwise; ^bSelf-rated health status dichotomised as good, very good or excellent vs. poor or fair; mean differences (95 % CI) derived from normal GEE models; and, OR (95 % CI) derived from binomial GEE models
