Agreements and disagreements with other
studies or reviews
These findings are similar to previous versions of this review,
and the findings of other reviews (e.g. Dyson 2009; Guise 2003;
Renfrew 1995), in that peer and professional support have been
shown to be effective interventions. We concur with others (e.g.
Hoddinott 2011; Renfrew 2007) that it is critically important to
identify the characteristics of support that may make this important
but heterogenous intervention more or less effective in different
circumstances.
