INS and diabetes mellitus: Older age (HR = 1.076, 95% CI = 1.014–1.143, p=0.016), elevated glucose level (HR = 1.153, 95% CI = 1.038–1.28, p=0.0079), increased serum amyloid A (SAA) (HR = 1.007, 95% CI = 1.001–1.014, p=0.022), diabetes treatment with only oral diabetes medication (HR = 0.152, 95%CI = 0.032–0.73, p=0.0036), and oral medication plus insulin (HR = 0.095, 95%CI = 0.019–0.462, p=0.019) were independent prognostic factors.
