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

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

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
  1. * 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).
