When Outcome measure data was originally and accurately posted for baseline and change after treatment, the time frames listed were 0 and 15 weeks, because the last assessment was gathered at approximately week 15 for each person whose data is in the data set. However, given the crossover design, it seems more accurate and understandable, to show the time frame for the outcome measure as 6 because the participants were each administered drug or placebo for six weeks total. (Of course for the Placebo then Study Drug arm, the placebo data was collected at week 6, and for the Study Drug then Placebo arm, the drug data was collected at week 6, and similarly for the first group the drug data was collected at week 15 (first assignment, plus 1 week titration, 2 weeks washout, new baseline at week 9, and final collection at week 15), and for the second group the placebo data was collected at week 15.
