Answer:
blind
Explanation:
To quantify the extent of atherosclerosis, each pathologist looked at every autopsy specimen and assigned a score. To keep the pathologists from knowing the source of the tissues beforehand, the study was <u>blind</u> to the pathologists.
Atherosclerosis is a disease resulting from the build up of fats around the arteries which could cause blood flow restriction or even bursting of the artery resulting in hemorrhage. It is more common in obesed individuals.
The advantage of blinding the pathologist from knowing the source of the tissues is to increase objectivity in their analysis and remove any form of biased judgement based on the source of the tissue. For example, if the pathologist is aware that the source of the tissue is from an extremely obese man, he/she may likely give it a higher score.
