All models were adjusted for seasonality based on day of year (DOY), DOW, ambient temperature, relative humidity, age, race, eGFR, lung diseases, diabetes mellitus, history of any chronic heart disease, smoking history, two or more alcoholic drinks per day, pack years of smoking cigarettes, ambient air pollutant exposures (no air pollution, PM2.5, BC, PN, or Log β) and solar variable (IMF(nt), Kp or SSN)
