Prevalence and temporal trend (2005-2015) of anaemia among children in Northeast Brazil.

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
objectiveAnaemia is the main nutritional deficiency in Brazil, and a prevention and control programme (National Program for Iron Supplementation) has been developed since 2005. Studies on the temporal evolution of anaemia prevalence contribute to assessment of the effectiveness of the actions undertaken. The present study aimed to identify the prevalence and temporal trend of anaemia in children.
designStudy based on two cross-sectional household surveys carried out in 2005 and 2015. Anaemia was defined as Hb<11 g/dl (HemoCue®). Trend analysis was performed using the prevalence ratio (PR), calculated by Poisson regression with a robust adjustment of the variance. Differences were significant when P<0·05 in both crude analyses and those adjusted for possible confounding factors (e.g. socio-economic, demographic and health variables).
settingAlagoas, Brazil. SUBJECTS: In total, 666 and 782 children in the first and second Alagoas State Health and Nutrition Survey, respectively (probabilistic samples).
resultsIn 2005 and 2015, anaemia prevalence was 45·1 and 27·4 %, respectively (-39·1 %; PR=0·61; 95 % CI 0·52, 0·70). In both surveys, children aged ≤24 months were more affected (P24 months (67·2 v. 40·7 %; 27·0 v. 19·3 %, respectively).
conclusionsThe prevalence of anaemia reduced significantly in the evaluated period. Thus, it may no longer be a severe public health problem but can instead be considered a problem of moderate magnitude. It remains, however, above the level considered acceptable according to WHO criteria. These results justify the implementation of prevention and control actions.
