In young, healthy men, having a higher body mass index is linked to higher heart output and stroke volume, while a larger waist-to-hip ratio is linked to lower heart output and stroke volume. This finding is from the abstract summary - full study details were not available
Scientific Claim
In healthy young men aged 18-22, higher body mass index is positively correlated with cardiac output and stroke volume, while higher waist-to-hip ratio is inversely correlated with both.
Original Statement
“Cardiac output and stroke volume were positively correlated to body mass index (p = 0.05 and p = 0.005), but inversely to waist/hip ratio (p = 0.01 and p = 0.01).”

Assessment Explanation
The abstract uses 'positively correlated' and 'inversely correlated', which correctly describes observational study findings without implying causation.
