Distribution and trend of CVs in frequency domain. A Distribution of \(FC\) expressed as median and quartile values. B Distribution of \({ER}_{5-300}\) expressed as median and quartile values. C Distribution of \({ER}_{300-500}\) expressed as median and quartile values. D Distribution of \({ER}_{500-1000}\) expressed as median and quartile values, where for ns, \(p>0.05\); *, \(p<0.05\); **, \(p<0.01\); ***, \(p<0.001\)
