Is hyperdynamic circulation a hallmark of obesity?
Article in International journal of obesity (2005), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03934775 (Identification of High-Risk Patients at Admission to an Emergency Department by Non-Invasive Hemodynamics), which is not on this 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.

Abstract
backgroundObesity is a major contributor to cardiovascular disease. Although altered central hemodynamics have been reported in obesity, studies are few, small, and limited to specific populations, leaving these changes underrecognized. This study investigates the association between body mass index (BMI) and central hemodynamics in a large cohort of adult patients admitted for medical reasons. We hypothesized that higher BMI is associated with increased cardiac index (CI) and reduced systemic vascular resistance (SVR), reflecting a hyperdynamic circulatory state.
methodsThis is a cross-sectional study of adults admitted to the Emergency Department at a large tertiary care hospital in Copenhagen, Denmark during 2019-2023. Patients were evaluated by physical examination and laboratory testing. Hemodynamic measurements, including CI and SVR, were estimated within 24 hours of admission using the non-invasive and continuous pulse wave analysis by Finapres® NOVA. The relationship between BMI, CI, and SVR were investigated using linear regression models.
resultsOf 942 participants (mean age 64 years; 44% female), 187 had obesity (BMI ≥ 30 kg/m²). Compared to participants without obesity, participants with obesity had 16% higher CI and 23% lower SVR (p < 0.0001). In linear regression models, BMI was positively associated with CI (p = 0.0001) and inversely with SVR (p = 0.0102). Each 5 kg/m² increase in BMI corresponded to a 7.7% rise in CI and a 12.7% decrease in SVR (p < 0.0001).
conclusionHigher BMI is significantly associated with increased CI and decreased SVR, indicating a hyperdynamic circulatory state in obesity. These findings suggest a potential hemodynamic mechanism linking obesity to cardiovascular risk. CLINICAL
