CD34 and ulcer disease: Adjusted models, correcting for sex, age, GFR, history of CVA, history of MI or Angina, presence of ulcers, higher triglyceride levels, and cholesterol levels, show higher HRs for PB PC numbers than unadjusted models (CD34+: HR = 0.71, p = 0.07, CD133+: HR = 0.64, p = 0.012).
