^blog-OR: log-odds ratio. A negative log-OR means a protective effect against severe obstructive coronary artery disease (SOCAD) requiring treatment with percutaneous coronary intervention or coronary artery bypass grafting on the premise that the presence of SOCAD was coded as 1 and non-SOCAD was coded as 0
