Seasonal variation of nutrient intake in pregnancy: effects on infant measures and possible influence on diseases related to season of birth.
Article in European journal of clinical nutrition, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 35 papers, 3 of them syntheses that pooled 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.
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
objectivesTo determine, firstly, if there was any seasonal effect on nutrient intake during pregnancy and birth measures, secondly, if there was any relationship between maternal nutrient intake and infant birth measures according to season and thirdly, to consider the hypothesis that seasonal change in nutrient intake during pregnancy might affect health in later life of some women's offspring.
designPilot study to determine number of days required to characterize group intake followed by a prospective cohort study.
settingPatients attending a city ante-natal clinic in the lower North Island, New Zealand. SUBJECTS: A total of 214 healthy mostly European pregnant women volunteers, entering the second trimester of pregnancy, of whom 10 miscarried and seven withdrew.
methodsSubjects were visited in months 4 and 7 of pregnancy, and months 2, 6 and 12 after birth. Height, weight and skinfolds were measured and questionnaires to determine personal details administered at these times. Subjects recorded 8 days of weighed diets in both the fourth and seventh month. Health records were used to supply infant measures.
resultsSignificant (P</=0.05) seasonal variations in fat, carbohydrate, vitamin C and D, B vitamins, beta-carotene, sodium, potassium, calcium, phosphorous, sulfur, sodium, chloride, zinc and selenium intakes were found. No significant 'main effect' difference in gestational age, infant birthweight, and head circumference was found with season. However, there were significant interactions (P</=0.05) for each birth season between birth measures and specific maternal nutrients at months 4 and 7 of pregnancy.
conclusionThe significant seasonal variations in nutrient intake in pregnant women, and significant influence of nutrient intake on birth measures in different seasons, suggests seasonal nutrient variation may also affect fetal development at a cellular level. This supports our hypothesis that the development of conditions related to season of birth, including schizophrenia, multiple sclerosis, type I diabetes and longevity, may be influenced by seasonal variation in nutrient intake during pregnancy.
