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 &

aimsThe aim of our study was to determine whether the use of iron supplements during pregnancy affects the risk for celiac disease in children.

methodsWe assessed data from the prospective Norwegian Mother and Child cohort study, in which individuals with celiac disease were identified by answers on questionnaires and linkage to the Norwegian Patient Register. Complete data were available for 78,846 children (mean age 5.9 years, range 2-12 years); 314 children were identified with celiac disease. Questionnaires were given to pregnant women to collect information on use of iron-containing supplements, diet, anemia, and levels of hemoglobin.

resultsCeliac disease was diagnosed in 4.65 of 1000 children whose mothers took iron supplements while they were pregnant, compared with 3.15 of 1000 children whose mothers did not. After adjusting for children's age, sex, and age of gluten introduction, and the presence of celiac disease in mothers, iron supplementation during pregnancy remained significantly associated with celiac disease in children (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.05-1.68; P = .019). However, celiac disease was not associated with the mothers' intake of iron from foods (adjusted OR, 1.00; 95% CI, 0.97-1.03). Anemia before or during the early stages of pregnancy was not significantly associated with the risk of celiac disease in children (adjusted OR, 1.24; 95% CI, 0.84-2.00; P = .24). The use of iron supplements during pregnancy remained significantly associated with celiac disease in children after adjusting for children who were given iron supplements before 18 months of age, which itself was associated with celiac disease.

conclusionsIn a prospective Norwegian Mother and Child cohort study, we found an increased risk of celiac disease in children whose mothers used iron supplements during pregnancy; this association does not appear to arise from maternal anemia.
