A Forest plot showing the results of a meta-analysis of post-treatment change in LVESV (in milliliters) for the patients who received image-guided or standard CRT. The pooled estimate favors image-guided CRT. Abbreviations: CI, confidence interval; CRT, cardiac resynchronization therapy; LVESV, left ventricular end-systolic volume; Lower limit, lower bound of the 95 % CI; Upper limit, upper bound of the 95 % CI
