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

Strong evidence that folic acid (FA) prevents the majority of cases of neural tube defects (NTDs) has led to national organisations developing guidelines for women concerning periconceptional supplementation. In Europe, there is evidence of national variations in the incidence of NTDs, with a recent Irish study reporting an increase in the rate. This review compares the periconceptional FA supplementation guidelines between the different countries in Europe. An online search of country-specific guidelines produced before 2015 concerning periconceptional FA supplementation was conducted. If an English version was not available directly, the EUROCAT register was searched for the English version of the recommendations. We identified national guidelines from 20 European countries. Over half recommended that FA supplements be taken by women planning a pregnancy, but three recommended that they should be taken by all women of child-bearing age. Four guidelines recommended starting FA at least 4 weeks preconceptionally, but no country recommended starting FA at least 12 weeks preconceptionally as suggested by recently published studies. There is a need for further consideration of the duration of preconceptional FA supplementation specifically. The latest scientific evidence in this area should inform the development of European guidelines on FA, as there is wide variation in current recommendations. Overall, the wide variation in national guidelines concerning periconceptional FA supplementation may in part explain the differences in national rates of NTDs reported by EUROCAT. National guidelines on FA supplementation should be standardised across European countries.
