Brazil's Bolsa Família conditional cash transfer and child malnutrition: a nationwide birth cohort study.

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
introductionPoverty amplifies the risk of malnutrition, which is particularly harmful to children as it can perpetuate a cycle of poverty and poor health. This study aims to assess the association of a conditional cash transfer programme (
methodsWe used the Centre for Data and Knowledge Integration for Health Birth Cohort (baseline data from the National Registry for Social Programmes (CadÚnico) linked with live births and nutrition registries) to conduct a longitudinal population-based study between 2008 and 2015. This cohort study followed children from birth until 5 years old between 1 January 2008 and 31 December 2015. Children exposed were those who received the BFP benefit at any time during follow-up and were compared with those who never received it. Malnutrition outcomes were assessed using height-for-age, weight-for-height and body mass index-for-age z-scores classified according to WHO cut-offs. Binary and multinomial logistic regressions and kernel-based matching were performed. Subgroup analyses considered maternal education and urban/rural areas of residence.
resultsOur cohort included 3 116 138 children born in Brazil between 2008 and 2015. BFP participation was associated with a 17% lower chance of stunting (OR 0.83; 95% CI 0.81 to 0.85). Additionally, BFP was associated with a 19% higher chance of wasting (OR 1.19; 95% CI 1.16 to 1.22). The protective association with stunting was more pronounced in children from less-educated mothers (OR 0.75; 95% CI 0.70 to 0.81) and those living in rural areas (OR 0.77; 95% CI 0.73 to 0.81). BFP participation was associated with higher overweight/obesity among children from mothers with 8 or more years of education and living in urban areas, while those with 3 or fewer years of education and living in rural areas experienced protective effects.
conclusionOur findings suggest a complex relationship between BFP participation and child malnutrition outcomes. The study underscores BFP participation's benefits in child nutritional outcomes, emphasising the programme's potential to reduce stunting in all children and to reduce overweight/obesity in the most vulnerable ones. However, BFP was also associated with an increased risk of overweight/obesity, which may be a consequence of overlapping stages of Brazil's rapid nutrition transition, a scenario that contributes to the double burden of malnutrition. Further research is needed to understand this finding better.
