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

objectiveConcerns have been raised about the nutritional adequacy of a gluten-free (GF) diet during pregnancy, specifically in the absence of celiac disease, and its impact on fetal development. The objective of this study was to investigate the association between a GF diet during pregnancy and obstetrical outcomes, with further sensitivity analyses exploring those without celiac disease.

methodsUsing data from the ongoing P3 Cohort study, self-reported data were obtained on participant demographics, GF diet, celiac disease, and obstetrical outcomes. Fisher exact, χ

resultsOf the 2359 participants included, 108 (4.6%) reported following a GF diet in pregnancy. The majority of these individuals (n = 68, 63.0%) were non-celiac. Participants in the GF group were older, more likely to identify as white, and more likely to take prenatal vitamin B supplements. There were no significant differences in obstetrical outcomes between the GF and non-GF participants. Sensitivity analyses excluding patients with celiac disease demonstrated similar results, with no difference in obstetrical outcomes observed.

conclusionFollowing a GF diet in pregnancy, even in individuals without celiac disease, was not associated with adverse obstetrical outcomes. These results provide some reassurance on the safety of a GF diet in pregnancy but require validation in larger studies.
