CL = confidence limit with 90% confidence interval for the mean. Observed changes are percentages; baseline values are expressed in measurement units. Likelihood that the true effect is substantial:
*possibly. Magnitude threshold: 0.20-0.59. Numbers in brackets indicate the % probability of a harmful, trivial and beneficial effect for both probability of group change and group inference. <0.20, trivial; 0.20-0.59, small; 0.60-1.19, moderate; >1.20, large.
