Distribution and trend of CVs in time domain. A Distribution of \(cv\) expressed as median and quartile values. B Distribution of \(E0\) expressed as median and quartile values. C Distribution of \(duration\) expressed as median and quartile values. D Distribution of \(frequency\) expressed as median and quartile values, where for ns, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001
