Our study selection process is illustrated in Figure 1. Of the 727 articles identified in our initial searches as potentially relevant, 39 studies met our selection criteria and were included in the meta-analysis. The characteristics of the included studies are shown in Table 1. These studies included a total of 1,140 patients who received MBT. The most common disorder studied was cancer (n = 9), followed by generalized anxiety disorder (n = 5), depression (n = 4), chronic fatigue syndrome (n = 3), panic disorder (n = 3), fibromyalgia (n = 3), chronic pain (n = 2), social anxiety disorder (n = 2), attention-deficit hyperactivity disorder (n = 1), arthritis (n = 1), binge eating disorder (n = 1), bipolar disorder (n = 1), diabetes (n = 1), heart disease (n = 1), hypothyroidism (n = 1), insomnia (n = 1), organ transplant (n = 1), stroke (n = 1), and traumatic brain injury (n = 1). Many studies targeted more than one disorder, and thus the sum of the above numbers exceeds the total number of studies included. In
