a decreasing trendp = 0.14not close (p > 0.1)

Similarly, a decreasing trend was observed in SampEn estimated from SSI, dP1, or dP2 ( p = 0.14), while the change of RRI SampEn was far from the statistical significance ( p = 0.50).

showed a trendp < 0.15not close (p > 0.1)

Interestingly, α 1 increased significantly for dP2 and showed a trend to increase ( p < 0.15) for dP1 while its increase was far from the statistical threshold for the reference RRI ( p = 0.69).
