Association Between Maternal Vitamin K2 Levels in Late Pregnancy and Newborn Bone Metabolism.
Article in Food science & nutrition, 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
We aimed to explore maternal vitamin K2 levels in late pregnancy and their association with neonatal bone metabolism markers. This study included 197 pregnant women and their matched newborns. Blood samples were collected from the mothers 1-2 days before delivery and from the umbilical cord immediately after birth. Serum vitamin K2 and 25-hydroxyvitamin D (25-OHD) levels were measured using liquid chromatography-tandem mass spectrometry. Maternal vitamin K2 levels were categorized into vitamin K2 deficiency (< 0.1 ng/mL) and normal (0.1-0.86 ng/mL) groups. Maternal vitamin K2 deficiency prevalence was 38.6%. Spearman's correlation analysis demonstrated a significant association between maternal vitamin K2 and newborn 25-OHD levels (
