BMI refers to body mass index. Perceived Stress Scale refers to the total score. PHQ-9 total refers to the Patient Health Questionnaire depression module total score. NSAID daily dose refers to average daily consumption of nonsteroidal anti-inflammatory drugs in 200 mg equivalent doses of ibuprofen, naproxen, and aspirin. Cigarettes per day calculated by average consumption over the past month. Scaled cannabis use indicates average use over the past year on a zero to two scale. Cotinine positivity indicates serum values of > 1 ng/mL, while tetrahydrocannabinol (THC) positivity indicates > 0.5 ng/mL. CRP refers to C-reactive protein serum level.
