  2. **COVID positive only.
  3. ***Cumulative logit models with GLM parameterization were used to estimate the log-odds of AI≥11 and adjusted for COVID/long COVID status, sex, age, race, BMI, smoking status, comorbidities, and lipids. Inflammatory and gut integrity markers were modeled separately from one another.
