Multivariate linear regression analysis further found differences in terms of FABP2 in groups HFs (% difference (95% confidence interval), 22.36 (8.04, 38.59), P = 0.01), HFM (3.16 (−12.62, 21.79), P > 0.05), and HFm (1.60(−14.89, 21.28), P > 0.05), compared with group HF0 (Table 2). This evidence concerns the gene FABP2 and Hand-foot syndrome.
