FABP5 and neoplasm: Although eight studies involving 995 patients indicated that FABP5 expression was significantly associated with tumor differentiation in patients from countries other than China (specifically Korea and Japan) (OR = 0.329, 95% CI = 0.144, 0.750, p = 0.008, I2 = 0.0%), the significance of this finding is limited by the geographic variations (Table 3, Figure 3D).
