The Table shows Zero and first order Spearman’s rho values between the change in plasma levels of LEA, OEA, POEA and NA-Gly and the change in state scores and heart rates after either rest or TM and the TM-selective (sTM) change in perceived pleasantness (N = 18–19). The changes (shown as ∆) were calculated as (post-minus the corresponding pre-treatment value). sTM refers to calculations designed to minimise any effects of time and rest and were calculated as (post-TM minus pre-TM) − (post-rest minus pre-rest). The first order Spearman correlation coefficients controlling for the time elapse between the two measurement occasions (“Gap”) or for the BMI at the start of the study were calculated by the method of Lehmann [56]
