BH, critical value for the Benjamini–Hochberg correction for multiple testing, (i/m)*Q, where i is the rank, m is the total number of tests (m = 34), and Q is the false discovery rate (Q = 0.10).
AVG_RR, average RR interval in millisecond MED_RR, median RR interval in millisecond SD_RR, standard deviation of the RR intervals SDARR, standard deviation of the aveages of RR intervals in all 5-min segments of the entire recording CVRR, coefficient of variance of RR intervals AVG_R, average rate SD_Rate, standard deviation rate SDSD, standard deviation of differences between adjacent RR intervals RMSSD, the root square of the mean of the sum of the squares of differences between adjacent RR intervals pRR50, percentage of number RR interval differences ≥ 50 msOCD, obsessive compulsive disorder
Note:aResult was still significant after the BH correction (P < BH).
