  1. Mean ± SD of HRV parameters of IHR (N = 1000 beats) of nine CAN+ and eight CAN- subjects. * significant (p < 0.05) difference between CAN+ and CAN-. # The values of d [see methods section for details] were found to be greater than 3 between SampEn and surrogated SampEn values of the two groups.
