Fig. 2From: A method for assessing robustness of the results of a star-shaped network meta-analysis under the unidentifiable consistency assumptiona A graphical representation of the evidence network for four smoking cessation counseling programs. b A graphical representation of the derived star-shaped network by eliminating four trials corresponding to direct comparisons among self-help, individual counseling, and group counseling. Each node represents an intervention, and a line between two nodes reflects one or more randomized controlled trials (RCTs). The numbers on each solid line connecting two interventions correspond to the number of RCTs comparing those interventionsBack to article page
