Prevalence of anaemia in Brazilian children in different epidemiological scenarios: an updated meta-analysis.
Synthesis in Public health nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 2 of them syntheses 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
objectiveTo update the estimation of the prevalence of anaemia in Brazilian children according to four different epidemiological scenarios.
designA new systematic review was conducted with a meta-analysis of the results published between 2007 and May 2019. Literature search was carried out in the PubMed and LILACS databases using keywords anaemia, child and Brazil. A total of thirty-seven articles (17 741 children) were selected and categorised according to the origin of their respective samples: childcare centres (Childcare; n 13 studies/2697 individuals), health services (Services; n 4/755), populations with social inequities (Inequities, n 7/6798) and population-based studies (Populations; n 13/7491). Assuming a prevalence of 20·9 % as reference (Health National Survey; n 3455), the combined prevalence ratios (PR) were calculated. A random-effects model was used.
participantsBrazilian children 6-60 months of age.
resultsThe prevalence of anaemia, by scenario, was: Childcare 24·8 % (PR 1·06; 95 % CI 0·81, 1·40); Services 39·9 % (PR 1·76, 95 % CI 1·33, 2·35); Inequities 51·6 % (PR 2·02, 95 % CI 1·87, 2·18); and Populations 35·8 % (PR 1·42, 95 % CI 1·23, 1·64). Therefore, the values were all higher than the national prevalence; the Inequities had the highest prevalence, and only Childcare did not reach statistical significance. Concerning the previous meta-analysis, there was a reduction in anaemia prevalence in all scenarios: -52·3, -33·7, -22·4 and -10·7 %, respectively.
conclusionsCompared to the situation revealed in the previous meta-analysis, anaemia, although observed to a lesser extent, remains an important public health problem in the different scenarios analysed, especially for children living in Inequities. Access to Childcare mitigates the risk for this condition.
