One was a cross-sectional study (Baharudin et al, 2014), one a pilot cluster randomised control trial (RCT) (Li et al, 2014), and two were treatment cohorts (Tiburcio & Natera, 2003;de los Angeles Cruz-Almanza et al, 2006). In the cluster RCT, two centres received the intervention and the other two received standard care.…”
