Prevalence of and factors associated with anemia in school children from Maceió, northeastern Brazil.
Article in BMC public health, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis that pooled it.
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
backgroundAnemia is a major public health problem in preschool children in Alagoas, Brazil, especially in the younger population, because of a positive correlation between hemoglobin level and age. However, due to the lack of studies, it is not known how widespread this condition is among older children or how it is associated with socioeconomic status. The aim of this study was to investigate the prevalence of and factors associated with anemia in school children from the city of Maceió, Alagoas state, Brazil. The analysis was stratified to identify any effect modification according to whether they attend public or private schools.
methodsA cross-sectional study was conducted using probability sampling of 1518 children (9.8 ± 0.5 years of age) attending public (n = 931) and private (n = 587) elementary schools in the municipality. Semi-structured questionnaires were used to obtain socioeconomic, demographic, anthropomorphic, hemoglobin (Hb), and dietary data. Anemia (Hb <11.5 g/dL) was the dependent variable. The measure of association used was prevalence ratio (PR) and respective CI95 %, calculated by Poisson regression with robust variance adjustment, for the crude and adjusted analyses.
resultsThe prevalence of anemia was found to be higher amongst the public school children than the private school children (10.8 % vs. 7.0 %; PR = 1.54; CI95 %: 1.1; 2.2). At the public schools, the variables that remained significantly associated with anemia after the multivariate analysis were "consumption of fruits/fruit juices < 2 portions/day" (PR = 2.19; CI95 %: 1.18; 4.06) and "male" (PR = 1.51; CI95 %: 1.001; 2.30). At the private schools, these variables were "working mother" (PR = 2.83; CI95 %: 1.23; 6.52) and "monthly school fees < R$ 188.00" (PR = 3.20; CI95 %: 1.46; 7.03).
conclusionsIn the population under study, anemia constitutes a major health problem, especially among children from public schools. Considering the associated factors and the fact that these children are in a school environment, the promotion of healthy eating habits could constitute an important approach for reducing the prevalence of anemia.
