Energy intake per day
5 RCT and cluster RCT No serious limitation Three studies presented data in Mean (SD) and two in Median (IQR) No serious indirectness No serious imprecision Strong association, no serious publication bias Mean: Pooled SMD: 0.76 (0.63-0.88) High
Median: Pooled SMD: 1.06 (0.87-1.24)
Feeding frequency per day
5 RCT and Cluster RCT No serious limitation Three studies had Means (SD) and two had % of feeding frequency >3/day No serious indirectness No serious imprecision Studies showed strong association. The pooled effective size for RR was not statistically significant. Mean: Pooled SMD: 0.48 (0.38-0.58) High
Frequency: Pooled RR: 0.99 (0.87-1.13)
