Linear regression analysis of the complexity parameters on age during STAND.

NCIHPMB, NCIHPLP, NCIHPCE = normalized complexity index of HP series derived from MB, LP and CE approaches respectively; NCISAPMB, NCISAPLP, NCISAPCE = normalized complexity index of SAP series derived from MB, LP and CE approaches respectively; NCIRESPMB, NCIRESPLP, NCIRESPCE = normalized complexity index of RESP series derived from MB, LP and CE approaches respectively; r = Pearson product-moment or Spearman rank order correlation coefficient; Yes/No = the variable is/is not significantly related to age with p<0.05.
