Table 4. Age is negatively correlated with power at slow wave activity saturation on induction and emergence.

Pearson’s correlations between age (in years) and the slow wave activity saturation parameters for Study 4. Age was strongly negatively correlated (r ~ -0.6, P<0.001) with Pswas on induction (P _{SWAS_I}) and emergence (P _{SWAS_E}), and with Ce _SWAS on emergence (Ce _{SWAS_E}). Significant correlations at the level of P<0.05 are highlighted in bold.
