Mean pre-scores minus mean post-scores in surgical technique. For Alpha-Theta (AT), SMR-Theta (SMR), and control (C) groups. In contrast to the control group, there is a significant increase in judges ratings' of both overall technique and particularly in the more difficult suture task for the SMR group. Marginal improvements are seen for the AT group although they are accompanied by large standard errors. Error bars signify the standard error of the mean (SEM).
