Notes from the review of this manuscript

Data collection was carried out between 2004 and 2006 for the comparison group and between 2009 and 2010 for the intervention group. Because these are non-overlapping periods, the effect of the intervention cannot be distinguished from contextual factors that may have changed between the two periods, such as economic condition.
