Which of the following outcomes was NOT measured in the Hambrecht Study?

The Hambrecht Study primarily focused on the effects of exercise training on patients with coronary artery disease, examining various cardiovascular outcomes. Specifically, it measured angina-free exercise capacity, which evaluates how much physical activity participants can perform without experiencing angina (chest pain), and myocardial perfusion, which assesses blood flow to the heart muscle during these activities. Cost-effectiveness of treatment might have been discussed in terms of the broader implications of the study, but specific metrics related to the economic evaluation were not the primary focus.

On the other hand, cognitive function improvements were not a focal point in this study. The primary aims revolved around physical and cardiovascular health improvements rather than mental or cognitive assessments. This distinction underscores that while cognitive function is an important aspect in various health studies, it was not a parameter structured into the measurements of this particular research. Thus, it is correct to conclude that cognitive function improvements were not measured in the Hambrecht Study.
