Table 2 shows the cohort response rate percentage for daily queries (medication, mood, and stress) and number of community board posts. Rates represent the average in the six-month period and are not cumulative (i.e. 6-month rates represent data from baseline through six months; 12-month rates represent data from six months through twelve months). Rates are only calculated for members who are missing less than 2 weeks of app data during the 6-month interval.
