M indicates mean. SD indicates standard deviation. d-values are estimates calculated using formulas 4.18 and 4.19 from Borenstein, Hedges, Higgins, & Rothstein (2009). d-values not calculated if unequal variances prevented pooling. Values in square brackets indicate the 95% confidence interval for each d-value The confidence interval is a plausible range of population d-values that could have caused the sample d-value (Cumming, 2014). *Post values of QIDS-C are only from hospital z.
