Role of Adipokines in Maternal Cardiac Function of Pregnancies Following Metabolic Bariatric Surgery.
Article in Obesity surgery, 2026. 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
objectiveMaternal metabolic bariatric surgery is associated with improved maternal cardiovascular function and an altered adipokine (adiponectin and leptin) levels. The aim of this study was to investigate whether adipokine levels mediate the improvement in maternal cardiovascular function reported in pregnant women with previous metabolic bariatric surgery.
methodsThe study included 41 pregnant women with previous metabolic bariatric surgery and 41 pregnant women without metabolic bariatric surgery but with similar early pregnancy body mass index (BMI). All participants underwent cardiac function assessment using two-dimensional echocardiography, at 11-14, 20-24 and 30-32 weeks of gestation. Maternal blood, collected at these three visits, was used for measurement of maternal adiponectin and leptin. Mixed-effects model analysis was used to assess the differences in adiponectin and leptin between groups, after adjustment for time, maternal age, ethnic group, parity, method of conception, BMI, smoking, gestational age at measurement and development of gestational diabetes mellitus. Pearson's correlation was used to assess the correlation of maternal adiponectin and leptin levels with cardiac indices.
resultsOverall, maternal adiponectin levels were higher in the post-metabolic bariatric surgery group, compared to the no surgery group (p = 0.008). However, leptin levels did not differ between groups (p = 0.76). Adiponectin levels were not associated with indices of maternal cardiac function including haemodynamics, cardiac geometry, diastolic, systolic and longitudinal function (p > 0.05). In contrast, maternal leptin levels positively correlated with maternal cardiac output in both the no surgery and post-metabolic bariatric surgery groups (p < 0.01 and p = 0.02, respectively).
conclusionsAlthough pre-pregnancy maternal metabolic bariatric surgery is associated with an improvement in maternal cardiac function, maternal adiponectin and leptin levels alone are unlikely to contribute to this improvement.
