Reduced rank regression-derived dietary patterns related to climate-sensitive micronutrients and their associations with child undernutrition among young children in rural Kenya: findings from the ALIMUS study.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUndernutrition among children remains a global public health challenge in sub-Saharan Africa. This study examined the associations of dietary patterns related to climate-sensitive micronutrients with undernutrition among children aged 6–23 months in Siaya County, Kenya.
methodsWe used cross-sectional baseline data of 626 mother-child pairs from a cluster-randomized controlled trial on nutrition counselling and home gardening. Dietary patterns and food intake were derived from a semi-quantitative food frequency questionnaire and identified using Reduced-Rank Regression (RRR) with the response variables of iron, zinc, selenium, and vitamin A (climate-sensitive micronutrients). Their associations with anthropometric z-scores [weight-for-age (WAZ), weight-for-height (WHZ), height-for-age (HAZ)] were calculated by regression models.
resultsIn this study population (median age: 15 months; 54.2% boys), boys had a lower median of WAZ (-0.47 vs. -0.20), WHZ (-0.02 vs. 0.18), and HAZ (-0.88 vs. -0.54) than girls (p < 0.05). RRR-derived dietary patterns were similar between boys and girls, explaining 68% and 65% of the variations in micronutrient intakes, respectively. These patterns, characterized by high consumption of vegetables, fish, potatoes, coffee and tea, white bread and cereals, fruits, rice and pasta, fermented food, and legumes, were positively associated with WAZ and WHZ but not with HAZ, only among girls.
conclusionA diet rich in protein sources and fruits and vegetables is associated with better general and acute nutritional status among young girls in rural Kenya.
