Figure 2. Network geometry used to assess the comparative effects of 22 nonpharmacologic interventions.

A, Adult with prehypertension to established hypertension. B, Patients with hypertension. The nodes represent 22 nonpharmacologic interventions and usual care. The size of every node is proportional to the number of randomly assigned participants (sample size). Each line represents a direct comparison, and the width of the lines is proportional to the number of studies comparing every pair of interventions. The coding guide, which provides a description of each intervention component, can be found in Table 1. DASH indicates Dietary Approaches to Stop Hypertension; MBSR, mindfulness‐based stress reduction; and PMR, progressive muscle relaxation.
