Prevalence of inadequate intake of folate after mandatory fortification: results from the first National Dietary Survey in Brazil.
Article in European journal of nutrition, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeOur aim was to estimate the prevalence of folate inadequacy (POFI) according to life stage, socio-economic status, and geographical regions after the mandatory fortification of wheat and maize flour in Brazil.
methodsThis was a population-based study. Data from two non-consecutive food records from the National Dietary Survey/Household Budget Survey 2008-2009 were used to estimate the usual dietary folate intake in µg dietary folate equivalents (DFEs). The National Cancer Institute method was used to account for within-person variance and the Estimated Average Requirement (EAR) cut-point method was used to calculate the POFI. The survey included 32,749 individuals, 15,700 males and 17,049 females, over 10 years old. Pregnant women, lactating women, and individuals with unreliable energy intake data were excluded.
resultsOverall POFI was 31.5% and mean dietary folate intake was 411.1 µg DFE. The lowest POFI occurred in the youngest age group of 10-13 years in both sexes, while the highest POFI was observed in the group ≥ 71 years. In women of childbearing age, POFI was around 32%. The lowest income strata had the highest POFI. The most developed regions (South and Southeast) had the lowest POFI compared to less developed regions.
conclusionsOur data show that folate inadequacy is still prevalent in Brazil mainly in low-income groups and less developed regions. Actions need to be taken to ensure that women of childbearing age, who presented a high prevalence of inadequate folate intake, achieve the recommended daily intake of 400 µg DFEs.
