HRV was measured immediately on admission to PACU and 2 h after surgery; this included variables of low-frequency power (LF), high-frequency power (HF), and LF/HF.
Univariate analyses were performed to assess the effect of variables on AMS and SDI; in order to estimate effect size multiple logistic regression was performed and this included variables previously associated with SDI, particularly in pSLE [ 5, 6, 48].
26 This index includes variables on: income, education, employment, occupation, housing and other variables such as disability, car ownership, internet access and single parents.
This depressive/dysphoric factor includes variables such as depressed mood, suicidal ideation and guilt [ 5, 8, 11].
This model includes variable blade-positioning angle β, the trajectory-shape coefficient CF, and the wind orientation angle φ.
This model includes variable cost factors, such as, transportation cost (equivalent energy content) as a function of distance, ash and moisture handling cost, and other miscellaneous costs.
This region, which includes variable region V6, was selected since it displays high variability (Fig. 1) and is surrounded by conserved regions [22], [23].
This study included variables related to the mammographic screening-protocol and women's personal characteristics.
This model included variables that differed at baseline between intervention and control or were associated with changes in outcome measures defined as p < 0.10.
