Kaplan-Meier plots: betaine.

<p>Plasma betaine concentrations and Kaplan-Meier plots of survival to events. Events: Top (A&B) death from all causes; (C&D) secondary myocardial infarction (MI); (E&F) hospitalization for heart failure (HF); (G&H) unstable angina (UA), and (H&I) all cardiovascular events. On left, A,C,E,G&H are subjects without diabetes; on right, B,D,F,H&J are subjects with diabetes. “High” (green) is the highest quintile of plasma betaine concentration, “Low” (red) the bottom quintile of plasma betaine concentration; “Middle” (black) the remaining 60% of the cohort. All significances are for comparisons with the middle group. Where no significance is shown, p for the difference is >0.3.
