Initial and Final Response and Remission Rates, Ratings of Global Functioning and Depression Severity, and Number of Treatments According to Treatment Group.

Intent-to-Treat Sample	Ultrabrief Pulse Right Unilateral ECT (N = 22)	Ultrabrief Pulse Bilateral ECT (N = 23)	Brief Pulse Right Unilateral ECT (N = 22)	Brief Pulse Bilateral ECT (N = 23)
Response Rates
Immediate post-ECT (%)	77	48	73	70
One-week post-ECT (%)	73^a	35^b	59^a	65^a
Remission Rates
Immediate post-ECT (%)	77^a	43^b	73^a	70^a
One-week post-ECT (%)^‖	73^a	35^b	59^a	65^a
CGI-I Response Rate (%)	82^a	35^b	64^a	65^a
Post-ECT GAS	64±12^a	51±15^b	63±11^a	62±12^a
Post-ECT BDI	10±11^a	19±19^b	11±8^a	10±12^a
Number of Treatments	8.7±2.4^a	8.9±2.5^a	8.5±2.5^a	6.2±2.4^b

Plus–minus values are means±SD. The treatment groups differed significantly in log-linear analyses or ANCOVAs, except in immediate response rate. Values with different letter superscripts for the same variable indicate that the corresponding treatment groups differed significantly from each other in post hoc pair-wise comparisons (P<0.05). Groups did not differ if they shared a superscript letter.
