Early childhood growth patterns and malnutrition in rural Southern India: a longitudinal study of a birth cohort.
Article in Frontiers in 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
Background: Malnutrition remains a pervasive problem among Indian children, but cross-sectional surveillance surveys and studies fail to identify secular trends and growth patterns. The study analyzed longitudinal data from the Longitudinal Indian Family hEalth (LIFE) birth cohort, established in 2009 to examine early childhood development. The field area for the LIFE cohort consists of rural to peri-urban villages in Medchal-Malkajgiri district, Telangana State, India, located approximately 40 km from Hyderabad, Telangana, India. This setting features predominantly agrarian households with socioeconomic challenges. Growth and malnurtition patterns in normal-birth-weight (NBW) and low-birth-weight (LBW) children were compared at multiple time points. Methods: Five hundred and forty children were included. Trained staff recorded height/weight via standardized methods every six months (± two months) until 24 months, then yearly until 60 months. Anthropometric indices were stunting (HAZ < -2 SD), wasting (WHZ < -2 SD), and underweight (WAZ < -2 SD). Group differences were analyzed using proportion tests and unpaired Results: WAZ, HAZ, and WHZ distributions remained below WHO reference curves throughout 6-60 months. Mean WAZ declined by 0.75 (NBW) and 0.40 (LBW); HAZ improved by 0.79 and 1.51, respectively. LBW-NBW differences in WAZ and HAZ narrowed rapidly after 3 and 2 years. Underweight prevalence rose from 18.8% (6 months) to 37.0% (36 months), stabilizing thereafter. Kaplan-Meier analysis showed 96% LBW vs. 87% NBW stunted, and 81% vs. 62% underweight by 60 months (steepest declines in first 18 months). Conclusion: Malnutrition significantly affects rural Southern India children, especially in the first three years, with LBW children and girls most at risk. LBW children demonstrated persistent acute and chronic malnutrition patterns until three years, after which the gradient between LBW and NBW reduced but never equalized, indicating the need for tailored nutritional supplementation.
