Number of vessels affected in different serum uric acid levels. The higher SUA quartiles were associated with higher incidence of 3-vessel disease, and the higher SUA quartiles were associated with lower incidence of normal vessel. And the incidence of 3-vessel in quartile 4 was significantly different as compared with those in other quartiles, but no significant difference was found among quartiles 1, 2, and 3; furthermore, the incidence of normal vessel in quartile 1 was significantly different with those of any other quartiles, and significant difference was also found between quartile 2 and 4, but no significant difference was found among other quartiles.
