Group comparisons were conducted using Chi-Square tests for categorical variables and generalized linear models for continuous variables (where P values refer to the main effect of BMI status). A significance level of P < .05 was used to determine statistical significance. PASC post-acute sequelae of SARS-CoV-2.
