Coagulation and inflammation markers and their relationship with MP in blood samples.

The β coefficient and P values were estimated using multivariate linear regression models. Multivariate linear regression models were used to adjust gender, age, education, job, marital status, smoking, alcohol, and physical inactivity; ^asignificance of the MP count group as a dichotomous variable in the multivariate linear regression model; ^bA significance of MP counts as a continuous variable in the multivariate linear regression model; MP microplastic, hsCRP C-reactive protein, PT platelet time, aPTT activated partial platelet time, ESR erythrocyte sedimentation rate.
