Table 1:
characteristics of the cohort, overall and separated based on outcome during acute course treatment. UBP survivors each received twelve RUL-UBP treatments. UBP censored patients discontinued ECT prior to the twelfth treatment, but had all treatments using RUL-UBP stimuli. UBP dropouts transitioned from RUL-UBP ECT to another stimulus type (brief pulse or bilateral electrode placement) prior to the twelfth treatment.
