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

Background and Aims: Evidence supporting the association between anaemia and lower iron intakes during pregnancy with an increased risk of childhood asthma remains unclear. This study aimed to investigate whether (i) lower haemoglobin or anaemia in late pregnancy and (ii) lower mean dietary iron intake in pregnancy were associated with a higher risk of childhood asthma. We hypothesised that lower maternal haemoglobin concentrations or anaemia, and lower mean dietary iron intakes, during pregnancy are associated with an increased risk of childhood asthma. Methods: This is a longitudinal study of mother-child dyads ( Results: In late pregnancy, the median (IQR) haemoglobin concentration was 11.7 (11.0, 12.2) g/dL and 21% ( Conclusion: Maternal anaemia and low dietary iron intake were not associated with childhood asthma in this longitudinal study.
