Significant modification effects of fat content on the associations between SPMA and erythroid-related hematologic parameters. The lines represent the associations (β, 95% CI), and P values for interaction effects are calculated by modeling an interaction term of SPMA and fat content in GLMs with adjustment for age, gender, smoking status, drinking status, work years, and workplace. *Ptrend < 0.05, by GLMs adjusted for age, gender, smoking status, drinking status, work years, and workplace
