HP and long COVID-19: As such, we used a multivariate logistic regression model adjusting for BMI and hypertension and found that higher levels of β-glucan (OR 1.4 per every 5-unit increase; P = 0.0048) and zonulin (OR 1.05 per every 5-unit increase; P = 0.038) remained associated with the PASC phenotype independently from BMI and/or hypertension (Figure 2L).
