Figure 4. Mean Severity of Subjective Adverse Effects and Percentages of Patients Experiencing Them.

For physical adverse effects, patients receiving electroconvulsive therapy (ECT) reported higher severity of headache (t_229.9 = 3.1; P = .002), nausea (t_225.8 = 2.8; P = .006), and muscle pain (t_201.9 = 3.7; P < .001) than patients receiving magnetic seizure therapy (MST). In the cognitive domain, patients receiving ECT reported higher severity of confusion or disorientation than those receiving MST (t_225.8 = 2.2; P = .03). The mood-related item scores, presented as positive effects rather than adverse effects, were similar between the 2 treatment groups.
