AB Overall network structure of the current network meta-analysis for the primary outcome of response rate. The lines between nodes represent direct comparisons in various trials, and the size of each circle is proportional to the number of participants receiving each specific treatment. The thickness of the lines is proportional to the number of trials connected to the network
