Factors Associated with Growth and Weight Status in Indigenous Children Under 5 Years of Age in Northeastern Brazil.
Article in Maternal and child health journal, 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
objectiveIndigenous children in Brazil experience persistent health and nutritional inequities, yet remain underrepresented in epidemiological research. This study investigated factors associated with the nutritional status of Indigenous children under 5 years in Northeastern Brazil.
methodsA cross-sectional household survey collected demographic, socioeconomic, maternal, perinatal, and anthropometric data of 329 children across 13 Indigenous communities in Alagoas, Brazil. Height-for-age (HAZ) and body mass index-for-age (BAZ) z-scores were calculated using the World Health Organization growth standards. Multiple linear regression models were used to estimate coefficients (β) and confidence intervals (95%CI) of factors associated with HAZ and BAZ.
resultsAmong 329 Indigenous children (52% boys, mean age [standard deviation, SD]: 2.4 [1.4] years), the mean HAZ was - 0.38 (SD: 1.09) and BAZ was 0.50 (SD: 1.10). Overall, 6.1% of children were stunted (HAZ <-2) and 9.5% were overweight (BAZ > + 2). HAZ was negatively associated with moderate or severe food insecurity (β: -0.37; 95%CI: -0.71, -0.03). Children living in masonry households (β: 0.71; 95%CI: 0.10, 1.32) and whose mothers were taller (β: 0.54; 95%CI: 0.24, 0.85) had higher HAZ. Regarding weight status, maternal underweight (β: -1.02; 95%CI: -2.00, -0.03) and cesarean section (β: 0.38; 95%CI: 0.14, 0.63) were significantly associated with BAZ. CONCLUSIONS FOR PRACTICE: Monitoring the nutritional status of Indigenous children is important in the first years of life. Strengthening traditional practices within Indigenous territories is essential for improved nutritional outcomes.
