Table 4 Correlations (r (p)) of heartrate-related measures with HEP (over frontal and central electrodes), cortisol levels and borderline symptom severity (BSL-23). Significant correlations are marked with * and printed in bold. These correlations survived Bonferroni correction (corrected for 6 factors, i.e. HEP frontal, HEP central, BSL-23, cortisol, heartrate and HRV-variables (whereby PNS index, SNS, Stress index, SDNN were pooled into a single one factor due to their close interrelation) resulting in p < 0.05/6 = 0.0083). Statistics of variables among each other and redundant results are not shown
