Correlation between each FDT item and autonomic neuronal function.

FDT ANS Spearman's rank correlation coefficient (ρ) p
Non-involvement suRR-HF 0.40 <0.05
Feeling of rejection suDBP-LF −0.33 <0.05

ANS, autonomic neuron function; suRR-HF, supine high-frequency component of the RR interval variability; suDBP-LF, supine low-frequency component of the DBP variability.
