In an alternate multivariate model including these two factors and SSc-related disease characteristics, lower EPC counts (P = 0.005), higher VEGF levels (P = 0.01), a history of digital ulcers (P = 0.04), and a modified Rodnan skin score > 14 (P < 0.0001) were independently associated with the late-NVC pattern. The gene discussed is VEGFA; the disease is systemic sclerosis.
