ORs of FLD for quintiles of RBC count were calculated with binary logistic regression analyses in different models, with Q1 as the reference.

Models: Model1, adjusted for age; Model2, adjusted for age and WC; Model3, adjusted for age, FPG, TG and HDL; Model4, adjusted for age, WC, FPG, TG and HDL. Sex was also adjusted in all the models of the total group.

P-interaction, interaction between sex and quintiles of RBC count.
