Abbreviations: CMR-ECT, control memory reactivation ECT; ECT, electroconvulsive therapy; EMR-ECT, emotional memory reactivation ECT; HDRS, Hamilton Depression Rating Scale (total score range: 0-52, with 0-7 indicating no depression and ≥24 indicating severe depression); RUL, right unilateral ECT.
a
The P values are not corrected for covariates and therefore differ from the P values from the multiple regression analyses in the results.
b
Two-sample t test.
c
Responders to ECT showed 50% or more decrease of symptom severity on the HDRS, and remitters showed an HDRS score 7 or less after the ECT course.
d
χ2 Test.
e
Mann-Whitney test.
