Note: ^a Number refers to the number of studies with a positive outcome relative to the number of studies with the intention present. These data based on 52 of the 70 comparisons. Excluded from these analyses were papers that involved community care, psycho-educational interventions in the community, internet interventions, health maintenance organisations, stand alone self help, or one of the trials where more than one contrast or subgroup was included. ^b Indicates that a sub category was significant.
