Q: 7
ACME Intervention Co. is testing a new carotid artery stent in patients with coronary artery disease,
in hopes of proving superiority over the current standard of care. After a subject signs consent, the
surgeon enrolls the patient and retrieves information on which stent to use, but the surgeon does
not share this information with the subject. Yesterday, the surgeon was instructed to use the control
stent. Today, the surgeon has completed two surgeries: the first one the surgeon was instructed to
use the control stent; the second one the surgeon was instructed to use the test stent. In what type
of trial is the surgeon participating?

C is correct here. Only the subject doesn't know which stent is used, so that's single-blind, not double-blind or crossover.
A or D
Leaning towards A because if the surgeon knows but not the subject, sounds kinda like double-blind, right? But not totally sure since the subject doesn’t know either. Let me know if you think otherwise.
