Note: Disease severity was determined by oxygen use in accordance with the Yale Impact Score: mild (no oxygen required), moderate (1–5 L oxygen use), severe (<5 L oxygen use). Pre-existing conditions were collected from hospital electronic records and self-reported at clinic visits: CVA cerebrovascular accident, COPD chronic obstructive pulmonary disease, DM diabetes mellitus, HTN high blood pressure. Values are presented as mean ± standard deviation or frequency (percent). * BMI = Body Mass Index, PCR = polymerase chain reaction, PASC = post-acute sequelae of COVID-19; 3 participants were mildly underweight (BMIs = 18.8, 19.4, 19.9).
