Pagnin et al. (2004) also include both the West et al. and Ulett et al. (1956) studies (but report the Ulett findings correctly as non-significant). Despite only one of seven studies (West, 1981) producing a significant difference, the studies do, when combined, find a significantly greater effect for ECT than for SECT at the end of treatment. The issue of differences beyond the end of treatment, however, is not even mentioned.
