Intake of iodine in a sample of UK mother-infant pairs, 6-12 months after birth: a cross-sectional study.

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
objectiveTo investigate the intake of iodine in mother-infant pairs.
designAn exploratory, cross-sectional study. Iodine intake was estimated using Nutritics nutritional analysis software, following 24-h dietary recall. Iodine-rich foods were grouped and compared between those women who met the UK reference nutrient intake (RNI) for iodine (140 µg/d) and those who did not.
settingOnline and telephone questionnaires.
participantsSelf-selecting caregivers of infants aged 6-12 months.
resultsNinety-one mother-infant pairs with a mean (sd) age of 33·2 (4·1) years and 8·4 (1·3) months, respectively, were included. Most mothers were exclusively breast-feeding (54·9 %). The estimated maternal median iodine intake from food and supplements (median 140·3 µg/d, just meeting the UK RNI for women of reproductive age, but not the World Health Organisation (WHO) or British Dietetic Association (BDA) recommendations for lactating women (250 µg/d and 200 µg/d, respectively). Forty-six (50·5 %) of mothers met the UK RNI. Estimated intakes of fish, eggs, cow's milk and yoghurt/cream/dairy desserts were significantly greater, whilst intakes of plant-based milk alternative drinks were significantly less in mothers who met the RNI for iodine (
conclusionsWomen in the UK may not consume enough iodine to meet the demands of lactation. Guidance on iodine-containing foods, focussed on intake before and during pregnancy and lactation and mandatory fortification of plant-based milk-alternatives could all serve to avoid deficiency.
