  1. SD = standard deviation.
  2. P = p-value.
  3. Part. Eta sq. = partial eta squared.
  4. Mean scores for the two groups are shown in columns Baseline and Follow-up and the change from baseline to follow-up in the columns Change. The results of the ANCOVA (statistical test of the difference between the groups at follow-up, adjusted for score at baseline) is revealed in columns P (significance level), and Partial Eta squared (effect size).
