Prevention of type 2 diabetes in adults with impaired glucose tolerance: the European Diabetes Prevention RCT in Newcastle upon Tyne, UK

Table 5 Mean (SD) of all years' annual change in secondary outcome measures: comparisonbetween sustained beneficial change* and no sustained beneficial change groups.

Outcome		Sustained beneficial change		No sustained beneficial change	Difference	p-value
	n	mean (SD)	n	mean (SD)	mean (95% CI)
Weight (Kg)	47	-4.1 (3.6)	36	2.3 (3.3)	-6.4 (-8.0, -4.9)	<.001
Activity(score/day)	37	11.1 (8.4)	31	-3.2 (17.5)	14.3 (7.8, 20.8)	<.001
Fibre intake (g/day)	30	4.4 (4.7)	39	-4.8 (4.5)	9.2 (7.0, 11.5)	<.001
Fat (% energy)	42	-6.3 (5.7)	32	1.4 (6.7)	-7.7 (-10.6, -4.8)	<.001
Carbohydrate (% energy)	31	5.0 (5.5)	38	-2.5 (6.2)	7.5 (4.7, 10.4)	<.001

* Sustained beneficial change in secondary outcome measures was defined as: a beneficial change (>0.01 units) maintained for two or more years (i.e. weight loss, reduction in % energy intake from fat, increase in % intake from carbohydrate, increase in intake of dietary fibre and increase in physical activity score).
