Example of a network diagram from a network meta-analysis: Interventions for acute diarrhea in children
The network diagram visually conveys the size and complexity of the network in NMA. This example shows the network diagram for an NMA that evaluated 62 clinical trials (20,256 participants) evaluating different treatments for acute diarrhea in children. The "nodes" (blue dots) represent different treatments; the size of each node corresponds to the number of participants who received that treatment. The "edges" (black lines connecting different pairs of dots) represent trial(s) directly comparing the 2 treatments; the thickness of the line corresponds to the number of trials.
