Furthermore, using the SPSS macro PROCESS 30 to analyze the total sample (adjusting for age and gender), NPY genotypes had a significant main effect on HF ( B = 0.10, SE = 0.04, t = 2.45, p = 0.014) and a marginally significant effect on RMSSD ( B = 0.04, SE = 0.02, t = 1.90, p = 0.058), but PSS scores were not.
