When men and women don't eat for 3 days, men tend to have higher levels of blood pressure, blood flow to arms, calorie burning rate, and stress hormones than women, but both sexes respond similarly to fasting.
Scientific Claim
In healthy young adults, acute starvation for 72 hours is associated with higher absolute values of blood pressure, forearm blood flow, metabolic rate, and plasma catecholamines in men compared to women, though the pattern of change during starvation is similar between sexes.
Original Statement
“Both sexes showed a similar pattern of response to starvation, although absolute values of blood pressure, forearm blood flow, metabolic rate and plasma catecholamines were higher in men than women.”

Assessment Explanation
The study design (cohort study) can describe associations between starvation and physiological changes. The claim uses 'is associated with' which appropriately reflects the observational nature of the study.
