  1. In CAPS-5 analyses, 108 participants met the cluster B clinical threshold at baseline (70 SGB and 38 Sham), 102 participants met for cluster C at baseline (66 SGB and 36 Sham), 106 participants met for cluster D at baseline (71 SGB and 35 Sham), and 111 participants met for cluster E at baseline (72 SGB and 39 Sham). In PCL-5 analyses,102 participants met the cluster B clinical threshold at baseline (66 SGB and 36 Sham), 90 participants met for cluster C at baseline (60 SGB and 30 Sham), 94 participants met for cluster D at baseline (64 SGB and 30 Sham), and 108 participants met forcluster E at baseline (70 SGB and 38 Sham).
