Baseline values are non-zero numbers because the analytical measurement range of the lidocaine assay is 0.6 – 8.0 mcg/mL, thus values below this linear range (including 0 values) may be reported as <0.6 mcg/mL.

Among those that received grafts.

Data are reported as mean (SD) or median (Q1, Q3) as appropriate.

CES-D: Center for Epidemiologic Studies – Depression Scale, STAI: State Trait Anxiety Inventory, CPB: cardiopulmonary bypass.
