Fig. 2.
Johnson–Neyman plot of the conditional effect of X (= Childhood Trauma, CTQ) on Y (= HRV, RMSSD) of moderator (= Attachment Insecurity, ECR). The dashed blue vertical line (mean attachment score = 4.69) represents the point where the relationship between Childhood Trauma and RMSSD transitions from statistically non-significant (red) to significant (blue) according to Johnson–Neyman analysis. Note: The range of observed values of attachment insecurity (ECR) is [1.73; 6.36]
