Maternal Galectins and Glucose Regulation in Pregnancy: Chronic vs. Acute Metabolic Adaptations.
Article in Diabetes & metabolism journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05496712 (Effect of Physical Activity in Pregnancy on Maternal and Fetal Human Milk Oligosaccharides), which is not on this map. Cited by 1 paper.
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.

Abstract
backgruoundGalectins (gal) are glycan-binding proteins that regulate maternal adaptations during pregnancy, but their role in pregnancy-associated metabolic homeostasis is unclear. This study characterizes the maternal galectin profile in response to an oral glucose tolerance test (OGTT) in pregnant women with varying body weight.
methodsIn a two-center prospective study, pregnant women were recruited into two cohorts: low-risk (LR) with normal weight and high-risk (HR) with overweight or obesity. Circulating levels of gal-1, -3, -7, and -9 were measured at fasting, 1 hour, and 2 hours during the OGTT between 24 and 28 weeks of gestation. Correlations with clinical and metabolic parameters were assessed (HMO study: ClinicalTrials.gov Identifier NCT05496712; FitFor2 trial: trial registration number NTR1139).
resultsFasting gal-3 and gal-9 were elevated in the HR cohort compared to the LR cohort. Body mass index was positively associated with gal-3 and gal-9, while gal-3 was also linked to insulin sensitivity. After glucose challenge, gal-1, -3, -7, and -9 decreased in the LR cohort; in the HR cohort, only gal-1 and gal-7 decreased after 2 hours, while gal-3 and gal-9 remained unchanged. Gal-1 correlated positively with homeostasis model assessment for insulin resistance (HOMA-IR) and inversely with insulin sensitivity across the OGTT in the LR cohort, but some of these correlations were not observed in the HR cohort.
conclusionGalectins exhibited distinct patterns of association with glucose homeostasis during the second trimester of pregnancy. Gal-3 and gal-9 are associated with chronic conditions such as pre-pregnancy obesity and insulin resistance, whereas gal-1 appears to be particularly sensitive to the acute glucose challenge.
