Survival estimates.

<p>Unadjusted Kaplan-Meier survival curve for all causes of death in diabetic subjects (<i>red lines</i>) and non-diabetic subjects (<i>blue lines</i>) grouped by age ≥50 (<i>dashed lines</i>) or age <50 (<i>solid lines</i>). Separate curves by age (dashed vs. solid) and diabetes (red vs. blue) illustrate the interaction of diabetes and age on survival. For age <50 the separation between diabetic vs. non-diabetic subjects is larger than for age ≥50.
