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.

Abstract

backgroundPericonception folate supplementation significantly reduces the risk of neural-tube defects, but few U.S. women start folate supplementation before pregnancy, and the amount of clinician time available to counsel patients about folate is limited. This study evaluated whether computer-assisted counseling and the provision of free folate tablets increases women's knowledge and use of folate supplements.

designRandomized controlled trial; follow-up began 6 months after enrollment and was completed on average 7 months after enrollment. SETTING/

participantsA total of 446 women, aged 18-45 years, were recruited from two urgent care clinics in San Francisco from March to July 2005 (data collection was completed in 2006; data were analyzed in 2007).

interventionParticipants received a 15-minute computerized educational session and 200 folate tablets.

main outcome measuresThe primary outcome was the knowledge that folate can prevent birth defects; secondary outcomes included the self-reported use of a folate supplement at follow-up.

resultsAt follow-up, women in the intervention group were more likely to know that folate prevents birth defects (46% vs 27%, relative risk [RR]=1.72, 95% CI=1.32, 2.23); to know that folate is most important in early pregnancy (36% vs 17%, RR=2.11, 95% CI=1.50, 2.97); and to report the recent use of a folate supplement (32% vs 21%, RR=1.54, 95% CI=1.12, 2.13).

conclusionsA one-time, brief, computerized counseling session about folate with the provision of free folate tablets increased the knowledge and use of folate supplements among women > or =6 months later.
