TMAO trimethylamine-N-oxide, 95% CI 95% confidence interval, T tertile, Ref reference, HbA1c glycated hemoglobin, HOMA-IR homeostatic model assessment of insulin resistance
Linear mixed-effects models were used to estimate the association between tertile of serum TMAO and the yearly changes of glycemic traits (fasting glucose, HbA1c, insulin, HOMA-IR) overt time. All models were adjusted for baseline age, sex, household income, smoking status, alcohol drinking, tea drinking, hypertension, WHR, physical activity, intakes of total energy, egg, red meat and processed meat, fish and shellfish, serum levels of TG, HDL-C and fasting glucose
