INFECTION, DYSFUNCTION, PAROSMIA, DISORDERS
For each patient, we collected following demographic data: sex, age, medical disorders, tobacco, alcohol, or other substance use, medications, prior history of olfactory dysfunction, prior treatment for COVID-19-associated olfactory disorders, and time elapsed since negative COVID-19 test. We created a medical record for each patient that included: the patient’s general medical and family health history, details on COVID-19 illness (date and symptoms at onset, date of positive and negative PCR-based SARS-CoV-2 testing, treatments during the infection, persistent symptoms, and treatments used after COVID-19 resolution), and data on COVID-19 vaccination. We also recorded detailed data on smell and taste alterations. After verbally explaining the differences between anosmia, hyposmia, parosmia, and phantosmia to patients and clarifying the difference between taste alteration and sense of smell/flavor, we queried patients about their history. At the end of the study (3 months after randomization and initiation of therapy), data were extracted and analyzed by a statistician, following procedures stipulated by the study coordinator (ADS).
