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.

Appropriate Language Strength
association
Can only show association/correlation
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.

Evidence from Studies
Supporting Evidence (1)
The study compared men and women during starvation and found that while absolute values of several parameters were higher in men, the pattern of change over time was similar between sexes.
