Association between mothers' fish intake during pregnancy and infants' sleep duration: a nationwide longitudinal study-The Japan Environment and Children's Study (JECS).
Article in European journal of nutrition, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
purposeN-3 polyunsaturated fatty acids (n-3 PUFAs), which are an important nutrient for humans, are particularly essential to the growth and development of the central nervous system (CNS) in fetuses and infants. Consequently, sufficient n-3 PUFA intake by mothers during pregnancy is considered to contribute to CNS development in their infants. CNS development is known to be associated with sleep, but no large epidemiological studies have yet confirmed that n-3 PUFA intake during pregnancy is associated with infants' sleep.
methodsAfter exclusion and multiple imputation from a dataset comprising 104 065 records from the Japan Environment and Children's Study (JECS), we examined 87 337 mother-child pairs for the association between mothers' fish and n-3 PUFA intakes and risk of their infants sleeping less than 11 h at 1 year of age.
resultsMultiple logistic regression analysis with the lowest quintile used as a reference revealed odds ratios for the second through fifth quintiles of 0.81 (95% confidence interval [95% CI] 0.76-0.87), 0.81 (95% CI 0.76-0.87), 0.78 (95% CI 0.72-0.84), and 0.82 (95% CI 0.76-0.88) for fish intake (p for trend < 0.001) and 0.90 (95% CI 0.84-0.97), 0.88 (95% CI 0.81-0.94), 0.88 (95% CI 0.82-0.95), and 0.93 (95% CI 0.86-0.998) for n-3 PUFA intake (p for trend = 0.04).
conclusionsLow fish intake during pregnancy may increase the risk of infants sleeping less than 11 h at 1 year of age. This relationship may have been mediated by maternal n-3 PUFA intake and infant neurodevelopment, but further evidence from interventional and other studies is needed to determine the appropriate level of fish intake during pregnancy.
