The article reports on the usage of Confidence Intervals (CIs) for data sampling, especially its importance with respect to the numeric side of the proposed Improving Access To Psychological Therapies (IAPT) programme by the Dept. of Health of London, England. It mentions that the usage of CIs helps to think better about numbers from personal and/or service's perspective, and to compare them with other data. CIs show how much precision we have gained for having an empirical sample.
