Furthermore, multivariate Cox regression analysis with the variables in Model 1 plus DM and hypertension (Model 2) as well as the variables in Model 2 plus eGFR, TGs, and steroid used (Model 3) showed that serum A-FABP levels were independently associated with first hospitalization events in KT patients (Model 2: HR = 1.015; 95% CI = 1.004–1.027; p = 0.009; Model 3: HR = 1.012; 95% CI = 1.000–1.025; p = 0.044) and a 1.2% increase in the risk of hospitalization events for every 1-ng/mL elevation in A-FABP serum levels in Model 3. This evidence concerns the gene FABP4 and hypertensive disorder.
