Abbreviations: Crl, Credible confidence interval; ICER, incremental cost-effectiveness ratio; nVNS, noninvasive vagus nerve stimulation; QALY, quality-adjusted life-year.
a
Incremental cost = average cost (nVNS with standard care) - average cost (standard care alone).
b
Negative costs indicate savings.
c
Results may appear inexact due to rounding.
d
Incremental effect = average effect (nVNS with standard care) - average effect (standard care alone).
