Daily 20-gram sachets of small-quantity lipid-based nutrient supplements (SQ-LNS) delivered remarkable nutritional improvements among 8,145 children aged 6-23 months in post-conflict Tigray, Ethiopia. The intervention group experienced a 17.6 percentage point reduction in acute malnutrition compared to just 6.1 points in controls, with mean weight-for-height z-scores improving by 0.72 units versus 0.16 in the control group. Most significantly, the entire population distribution of weight-for-height shifted rightward, indicating systemic nutritional uplift rather than merely treating the most malnourished children. This population-level effect represents a paradigm shift from traditional targeted interventions to universal nutritional enhancement. The findings are particularly compelling given the post-conflict setting where malnutrition rates had reached emergency levels above 20%. However, this was a non-randomized cluster trial rather than a gold-standard randomized controlled trial, which may introduce selection bias. Additionally, as a preprint awaiting peer review, these results require validation before informing policy. The dramatic effect sizes—among the largest reported for nutritional interventions—suggest either exceptional intervention effectiveness or potential methodological limitations that peer review will need to address.
