They were divided into two groups: normal levels of uric acid (UA) (NUA, n = 44) and high levels of UA (HUA, n = 61) with matching sexes.

FABP1 was positively correlated with UA (r=0.390, <jats:italic>P<\/jats:italic>=0.002) in the HUA group. The correlation still existed after adjusting for confounding factors. Preoperative FABP1 levels were risk factors for hyperuricemia at baseline. UA and FABP1 levels decreased at 3, 6, and 12 months postoperatively. FABP1 showed a more significant decrease in the HUA group than in the NUA group at 12 months (27.06 \u00b1 10.98 ng\/mL vs. 9.54 \u00b1 6.52 ng\/mL, <jats:italic>P<\/jats:italic>=0.003).
