Micronutrient dynamics and deficiency risk across pregnancy and postpartum in a Slovak cohort.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 assess the dynamics in blood concentrations of vitamins (A, B6, B12, D, E,), trace elements such as selenium, magnesium, zinc, and iron (transferrin), and metabolite homocysteine during pregnancy and postpartum.
designCross-sectional, national cohort study conducted between January and June 2024.
settingSlovakia. POPULATION: Pregnant and postpartum women.
methodsFrom venous blood and capillary dry blood spot micronutrients were analysed using standard biochemical and biophysical methods.
main outcome measuresGroup differences in blood micronutrient levels across pregnancy and postpartum.
resultsOur findings reveal significant differences in maternal micronutrient levels across pregnancy and postpartum. While some nutrients, including vitamin D and folate, remained relatively stable, others such as vitamin A, B12, iron and zinc were observed at lower levels, and vitamin E at higher levels during pregnancy. Vitamin E levels in the 3rd trimester frequently exceeded reference values for the general adult population, whereas zinc levels were significantly lower postpartum. We observed high prevalence of vitamin B12 and iron deficiencies, as indicated by transferrin saturation, particularly in the 3rd trimester. Vitamin D deficiency was prevalent throughout pregnancy and postpartum. Finally, our analysis demonstrated that dried blood spot (DBS) technology provides comparable results to venous blood analysis for measuring vitamin A, D and homocysteine levels.
