From: Cardiovascular outcomes in trials of new antidiabetic drug classes: a network meta-analysis
Network profile for the included trials comparing different antidiabetic drug classes. Each line represents a pair of direct comparison between different antidiabetic drug classes while each dotted line represents the missing comparison. The width of the lines is proportional to the number of trials comparing every pair of treatments, and the size of every circle is proportional to the number of randomly assigned participants (sample size)
