Association of Maternal Overweight/Obesity Metabolic Phenotypes With Longitudinal Foetal Anthropometric Measurements.

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
aimsTo examine the associations between early-pregnancy maternal overweight/obesity metabolic phenotypes and foetal anthropometric measurements and assess mediation by gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH).
methodsThis study included 7633 pregnant women from a Chinese prospective cohort. Participants in early pregnancy were classified as metabolically healthy normal weight (MHNW), metabolically unhealthy normal weight (MUNW), metabolically healthy overweight/obesity (MHO) and metabolically unhealthy overweight/obesity (MUO). Generalised linear mixed models evaluated associations with repeated ultrasound measures for participants with at least one scan between 22 and 36 weeks. Mediation analyses evaluated GDM and PIH effects.
resultsCompared to MHNW, both MHO and MUO were associated with higher estimated foetal weight (EFW) and abdominal circumference (AC) Z-scores mainly during 28-36 weeks, as well as an elevated risk of foetal EFW and AC overgrowth. Furthermore, the MUO increased the risk of head circumference (HC) undergrowth (OR = 1.22, 95% CI: 1.00-1.48). Conversely, the MUNW was associated with lower foetal HC Z-scores (β = -0.05, 95% CI: -0.10 to 0.00). In addition, GDM mediated the association between MUNW and reduced foetal HC Z-scores at 28-32 and 33-36 weeks, with mediation proportions of 11.2% and 16.1%, respectively.
conclusionsEarly-pregnancy maternal overweight/obesity metabolic phenotypes are associated with foetal growth. MHO and MUO increase EFW and AC overgrowth risks, while MUO also raises HC undergrowth risk. Conversely, MUNW is associated with a reduced HC Z-score, a pathway mediated by GDM. These findings highlight that the joint assessment of body mass index and metabolic health is vital for targeted maternal care.
