Fig. 3From: Image-guided left ventricular lead placement in cardiac resynchronization therapy for patients with heart failure: a meta-analysisA Forest plot showing the results of a meta-analysis of post-treatment change in LVEF (A) and the corresponding sensitivity-analysis (B) for the patients who received image-guided or standard CRT. (A) The pooled estimate favors image-guided CRT. (B) The pooled estimates of all 3 studies and each pair are similar. Abbreviations: CI, confidence interval; CRT, cardiac resynchronization therapy; LVEF, left ventricular ejection fraction; Lower limit, lower bound of the 95Â % CI; Upper limit, upper bound of the 95Â % CIBack to article page
