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

backgroundIt has been proven that periconceptional folic acid (FA) supplementation could prevent neural tube defects. However, FA supplementation during different stages of pregnancy and its association with the neurobehavioral development of offspring remains unclear, particularly the effects of continued FA supplementation during the second and third trimesters. This study aimed to investigate the relationship between maternal FA supplementation at various stages of pregnancy and infant neurobehavioral development.

methodsIn a prospective birth cohort study involving 3246 parent-child pairs, 2905 infants completed neurobehavioral development assessments at 6 months and 3005 infants at 18 months. Information regarding micronutrient supplementation at various stages of pregnancy was recorded. Multivariable logistic regression was used to evaluate the association between FA supplementation and infant neurobehavioral developmental delays. In addition, propensity score analysis was performed to correct the potential imbalances in the distribution of related factors between the groups.

resultsDuring the periconceptional period, maternal standardized FA supplementation (taking 0.4 mg FA daily before and in early pregnancy, as officially recommended) was associated with a reduced risk of possible development delays in 18-month-old infants in the communication domain (RR = 0.48, 95% CI: 0.26-0.86; P = 0.015). After the 12th gestational week, maternal continuous FA supplementation in the second and third trimesters was significantly associated with a decreased risk of possible neurobehavioral development delay in 6-month-old infants in fine motor domain (RR = 0.31, 95% CI: 0.12-0.82; P = 0.019) and the problem-solving domain (RR = 0.20, 95% CI: 0.05-0.79; P = 0.022). These associations remained significant after adjusting for confounders and propensity scores.

conclusionsFA supplementation at different stages of pregnancy may enhance neurobehavioral development in offspring. To confirm these findings, additional investigations or trials with larger sample sizes and consistent tracking of folate status throughout pregnancy are recommended.
