Figure 3:

Primary cognitive outcomes (Hopkins Verbal Learning Test-Revised Retention Raw Scores, HVLT-R Retention Raw Score) for right unilateral electrode placement. For legend, see Figure 2.

Figure 3A: Longitudinal changes within each amplitude. HVLT-R Retention Raw Score performance was similar throughout the ECT series for each amplitude arm (see Figure 2A for figure legend).

Figure 3B: Amplitude contrasts at each assessment: Amplitude arms did not have HVLT-R Retention Raw Score differences at the mid- or post-ECT assessments.

Figure 3C: Sex differences. Male and female subjects did not have HVLT-R Retention Raw Score performance differences.

Figure 3D: Pulse width differences. Brief (1.0) and ultrabrief (0.3) pulse widths did not have HVLT-R Retention Raw Score differences.
