Nutrition systems strengthening interventions targeting children vs no intervention or standard care to reduce stunting (height‐for‐age, length at 18 months)

Mean height‐for‐age z‐score · children under 5 years old

Nutrition systems strengthening interventions targeting children may leads to higher height‐for‐age (z‐score) at 18 months compared with no intervention or standard care to reduce stunting (height‐for‐age,… (low certainty).
