نبذة مختصرة : OBJECTIVE Trimethylamine N-oxide (TMAO) is suggested as an independent gut microbiota-derived risk factor for cardiovascular and renal disease. We investigated associations between plasma TMAO concentrations and cardio-renal outcomes in a prospective study of individuals with type 1 diabetes. RESEARCH DESIGN AND METHODS Plasma TMAO was measured at baseline in 1,159 individuals with type 1 diabetes (58% male, mean +/- SD age 46 +/- 13 years). End points were all-cause and cardiovascular mortality, cardiovascular disease (CVD), and renal events tracked from national registries. Associations between TMAO and end points were tested using Cox regression models. RESULTS After 15.0 (6.7-19.3) (median [interquartile range]) years of follow-up, we recorded all-cause and cardiovascular mortality (n = 363 and 120, respectively), combined CVD (n = 406), coronary outcome (myocardial infarction and coronary intervention) (n = 163), stroke (n = 115), hospitalization for heart failure (n = 81), and end-stage renal disease (n = 144). In univariate analyses, higher TMAO concentrations were associated with all end points (P
