Loess spline curves of long-term LVEF trajectories. LVEF trajectory comparison between diabetic (orange) vs. non-diabetic (blue) patients. P for trajectory changes on LVEF < 0.001 for both groups. P for comparison between groups (interaction between trajectory changes and diabetes) = 0.009. Shaded regions displayed around curves represent the confidence interval at level = 0.95
