So, from HR and HRV signals obtaining from this model, linear features such as Mean, Median, Variance, Standard Deviation, Maximum Range, Minimum Range, Mode, Amplitude Range and frequency spectrum, and non-linear features such as Lyapunov Exponent, Shanon Entropy, log Entropy, Threshold Entropy...
Heart rate variability (HRV), the analysis of beat-to-beat changes in heart rate, is a noninvasive indicator of autonomic tone that might be useful in the identification of patients who are at risk for weaning difficulty due to underlying cardiac dysfunction. The authors describe HRV and ...
Analysis of variance was used to identify alterations in the proportion of interval differences exceeding the minimum over ages and sleep-waking states, and to describe developments in the temporal patterns of cardiac interval changes. At all ages, infants showed fewer beat-to-beat interval changes ...

Analysis of variance (ANOVA) and Kruskal–Wallis tests were used to evaluate differences between continuous variables. Correlations between continuous variables were assessed using Pearson’s and Spearmans’ tests. The triglycerides variable was naturally logarithmically transformed to normalize its ...
We used one way analysis of variance (ANOVA) to test for the overall differences among groups, followed by Gabriel's method to compare the sepa- rate group means when the Levene test was not significant, and followed with the Dunnett-T3 method to compare those when the Levene test was ...
(proximal-LADvs. mid-LADvs.distal-LAD) were assessed by analysis of variance with subgroup analysis by Student-Neumann-Keuls test. All analyses were two-sided. Statistical significance was set atP< 0.05. All statistical calculations were performed using SPSS for windows, release 20.0 (Chicago, ...
