Fig. 1From: Comparisons of exacerbations and mortality among LAMA/LABA combinations in stable chronic obstructive pulmonary disease: systematic review and Bayesian network meta-analysisNetwork geometry of the direct comparison in the eligible 16 RCTs. Network (a) expressed individual drugs or their combinations as each node, and a direct comparison of two different treatments in an RCT was shown as a line between nodes. Network (b) combined all inhaled treatments other than individual LAMA/LABAs to each drug class (ICS/LAMA/LABA, ICS/LABA, LAMA, and LABA) and expressed them as each node. The number of direct comparison was expressed as a number in the middle of a line between nodes.
