From: Is CRT-D superior to CRT-P in patients with nonischemic cardiomyopathy?
Forest plot demonstrating impact of CRT-D on long-term (> 1 year) mortality in patients with NICM compared to CRT-P. In patients with NICM and indication for CRT and ICD: CRT-D was associated with lower all-cause mortality (log HR − 0.169, SE 0.055; p = 0.002) compared to CRT-P. Heterogeneity: df = 15 (P 0.03), I2 = 43; Test for overall effect: Z = − 3.043 (P = 0.002)
