The majority of patients who participated in this study had completed a higher qualification so our findings may not be applicable to a wider population group.
Results that are statistically and clinically significant might be robust enough to serve as the basis for health policies that could benefit wide population groups.
Thus, the supply to wide population groups was not easy nor quick, and this was a logistic problem that usually restricted and delayed the use of the vaccine to control outbreaks.
In this Cochrane Review, we assessed whether the estimate of effect observed only in RCTs is of similar magnitude to those seen in previous reviews and the applicability of hand washing interventions in reducing diarrhoeal diseases across wide population groups.
Although the pooled estimates reject the proposal that vitamin E supplementation would be beneficial for wide-ranging population groups, our study suggests that important subgroups being harmed or benefiting from vitamin E may be hidden in the misleadingly narrow confidence intervals.
More recently, activation principles have been extended to cover a wider range of population groups, and increasingly in a co-ordinated manner across policy domains.
A wider range of population groups use care farms and these will be captured by the review.
Generic instruments do not focus on a particular condition, and therefore can be applied to a wide range of population groups as they are broad in scope, e.g. Euro-QoL (EQ-5D), Short Form Health Survey (SF-12) [ 13, 14].
The ceiling effects can be expected with generic HRQOL instruments since they are designed to apply to a wide range of population groups.
Since the doubly labeled water (DLW) method has been established as an important tool for the measurement of total energy expenditure (TEE) in man, there have been many reports detailing TEE from a wide range of population groups under free-living conditions.
