In Table 3, under the fifth heading, QOL--general health (MOS SF-36), there are several incorrect values.
In the first row, labeled T1 baseline, in the columns under the grouping Experimental Group (MBSR[BC]), Mean is recorded as 39.43 and SD is recorded as 24.4, whereas Mean should be 62.63 and SD should be 21.24. In the columns under the grouping Control Group (UC), Mean is recorded as 31.84 and SD is recorded as 24.5, whereas Mean should be 66.29 and SD should be 20.76.
In the second row, labeled T2 week 6, in the columns under the grouping Experimental Group (MBSR[BC]), Mean is recorded as 28.51 and SD is recorded as 24.04, whereas Mean should be 67.93 and SD should be 19.87. In the columns under the grouping Control Group (UC), Mean is recorded as 29.87 and SD is recorded as 25.7, whereas Mean should be 68.28 and SD should be 21.28. In the columns under the grouping Between-Groups Effect Size Adjusting for Baseline, d is recorded as 0.46 and 95% CI is recorded as 0.25 to 0.66, whereas d should be 0.16 and 95% CI should be -0.04 to 0.37.
In the third row, labeled T3 week 12, in the columns under the grouping Experimental Group (MBSR[BC]), Mean is recorded as 28.36 and SD is recorded as 24.54, whereas Mean should be 68.76 and SD should be 21.50. In the columns under the grouping Control Group (UC), Mean is recorded as 28.01 and SD is recorded as 26.01, whereas Mean should be 67.85 and SD should be 21.99. In the columns under the grouping Between-Groups Effect Size Adjusting for Baseline, d is recorded as 0.35 and 95% CI is recorded as 0.15 to 0.56, whereas d should be 0.21 and 95% CI should be 0.01 to 0.42.
