Placental cadmium and its association with maternal diet and offspring growth in Koreans.

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
BACKGROUND/
objectivesCadmium (Cd) can cross the placental barrier and affect fetal development. Dietary exposure is a primary source of Cd intake. However, studies examining the relationships between food intake, placental Cd concentration, and offspring growth remain limited, especially in Asian populations. This study aimed to identify foods and cooking methods that contribute to placental Cd concentration and assess the association between placental Cd concentration and infant growth. SUBJECTS/
methodsThis study analyzed 72 non-smoking pregnant women and their placentas. Food intake during late pregnancy was assessed using a food frequency questionnaire and categorized based on main ingredients and cooking methods. Placental Cd concentration was measured using an inductively coupled plasma mass spectrometer. Neonatal anthropometrics were obtained from medical records, while 1-yr anthropometrics were collected through interviews.
resultsPlacental Cd concentration was not associated with intakes of foods when categorized according to main ingredients; however, positive associations with the intake of boiled and deep-fried foods were observed (β = 0.350 and 0.739, respectively; both
conclusionPlacental Cd concentration may be associated with the consumption of boiled and deep-fried foods during late pregnancy, rather than intake of a certain food group categorized by main ingredient. The observed trend of increased placental efficiency despite lower birth weight and length in female infants suggests that the placenta may function as a barrier to Cd sex-specifically, potentially mitigating its effects on offspring development.
