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

objectiveTo investigate the awareness and use of folic acid in European women of child-bearing age, particularly in the setting of pregnancy and pregnancy planning.

methodsBetween November 2009 and December 2009, women aged 15-49 years old from 18 European countries completed a 30-minute structured questionnaire either online or via face-to-face interviews. To achieve nationally representative samples for each country quotas were set for age, education, income, and regional distribution.

resultsA total of 22,925 women participated in the survey. Of the respondents, 58% had at least one biological child, and of these 38% reported that their first pregnancy was not planned. Nearly 60% of women who planned their pregnancy indicated that they had stopped using their method of contraception without first consulting a doctor or another health care professional. Overall, 70% reported that they had heard of folic acid and 40% stated that they knew the benefits of folic acid. However, when prompted to indicate which diseases and/or birth defects folic acid can protect against, only 17% knew that folic acid can reduce the risk of neural tube defects/spina bifida.

conclusionsA large proportion of European women of child-bearing age in this survey were unaware that periconceptional folic acid supplementation reduces the risk of birth defects.
