aIn one study, Rollins 2007, children were included that were treated on an inpatient and outpatient basis. bOf the seven studies on macronutrients, one study recruited and treated people in a hospital setting (Pérez‐Guzmán 2005). cOne study included Aboriginal children. dSix studies included nutritionally‐at‐risk children, whereas in two studies there were no trial entry criteria based on child nutritional status. eFive studies appeared in both Kristjansson 2015a and Sguassero 2012.
