The participants were divided into two groups. One group, 71 people, received Mindfulness Based Cognitive Therapy (MBCT) as well as Treatment-As-Usual (TAU), and the other group, 66 people, received only TAU (sixth corruption). At the end of the 60 weeks, they found that out of the 71 people in the MBCT group, 31 had relapsed (44 per cent); and out of 66 in the TAU group, 38 people relapsed (58 per cent). This leaves us with the result that just 14 per cent fewer people having relapsed in the treatment group at the end of one year. This is the total benefit: 14 per cent additional people did not relapse. In other words, the treatment was of benefit to about 1 or 2 out of 10 people. It is always instructive to state the reverse: 8 or 9 out of 10 people were not helped by the treatment. Interestingly, these figures are never stated in this form in the paper.
