FGF21 and coronary artery disorder: Therefore, we performed a sensitivity analysis by excluding the case-control study without multivariate HR (25), and an independent and significant association between higher FGF21 levels and the risk of all-cause death was found in patients with CAD (HR: 2.67, 95% CI: 1.25–5.72, P < 0.05, I2 = 64%, random-effect model; Figure 3B).
