Comparison of procedural and follow-up outcomes with different CRT techniques. Estimation of the effect of the different pacing modalities has been obtained from pooled data from the references. Green has been added when both comparisons with the alternative groups are favorable; yellow shows if one of the comparisons is favorable and the other is neutral; orange shows one comparison is favorable and the other unfavorable; and red shows when both comparisons are unfavorable.
