HRV changes (pre-to-post differences) within the three treatment groups. Plots from results of estimated marginal means with pre-to-post differences per group indicating improved HRV for Meditation Based Lifestyle Modification (MBLM), almost no changes for drug continuation therapy (MINIMAL treatment), and deterioration for treatment as usual (TAU); (A) Differences in meanNN (average beat-to-beat interval as negative pendant to average heart rate); (B) Differences in RMSSD (root mean square of successive beat-to-beat interval differences as measure for short-term or vagal activity); (C) Differences in symdynrenyi4 (Renyi4 entropy of symbolic dynamic patterns in the beat-to-beat interval series as measure for its complexity).
