1 · What the graph read from 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.

2 · The registry

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

objectiveIncreasing evidence has suggested an association between food insecurity and the risk of anaemia. Therefore, a systematic review and meta-analysis were performed to examine the associations between food insecurity and anaemia risk.

settingPertinent studies were identified by searching PubMed and EMBASE databases up to August 2017. Data were available from nineteen studies; seventeen studies were cross-sectional and two studies were longitudinal. Risk ratios of 95993 individual participants from twelve different countries in these studies were pooled for the meta-analysis.

resultsThe results showed that there was an overall positive relationship between food insecurity and anaemia risk (OR=1·27; 95 % CI 1·13, 1·40). Similar results were observed for Fe-deficiency anaemia (OR=1·45; 95 % CI 1·04, 1·86). These results revealed that food insecurity at two levels, including mild food insecurity (OR=1·15; 95 % CI 1·00, 1·31) and moderate food insecurity (OR=1·36; 95 % CI 1·23, 1·48), increased the risk of anaemia. In addition, it was found that age had an impact on the associations between food insecurity and anaemia risk (OR=1·22; 95 % CI 1·09, 1·36). Age subgroup analysis indicated that food insecurity significantly increased the risk of anaemia among infants/toddlers (OR=1·17; 95 % CI 1·05, 1·29) and adult women (OR=1·35; 95 % CI 1·16, 1·54).

conclusionsIt seems that infants, toddlers and adult women in food-insecure households are at a higher risk of anaemia. To prevent anaemia in food-insecure households, these age groups may require more nutritional support.
