The mean PANSS visit response results were likely impacted by the rate of early discontinuation and the treatment-group difference in discontinuation due to lack of efficacy.
As previously reported, the baseline visit response rate was lower than expected; older youth, African American youth, and those with type 2 diabetes were less likely to complete a visit (26).
All lesions specified at baseline were followed over the course of the study with last observations carried forward for any lesions not measurable at a visit; response assessment was censored for missed visits.
Considering a visit response of 90% [ 16] and assuming a loss-to-follow up of 30%, at least 2450 children per group will participate in outcome measurement at 6 years.
Such results also support the process of cross-cultural harmonization of issues, as facilitators re-visit responses and compare similar statements of different respondents in light of new information about potential group and cultural differences.
To investigate factors associated with pesticide-related visits to health care providers (i.e., doctor or hospital visits), responses to self-administered questionnaires received from 35,879 licensed restricted-use pesticide applicators participating in the Agricultural Health Study were analyzed.
Of participants still alive at the time of follow-up visits, response rates for visits 2, 3, and 4 were 93, 86, and 81%, respectively.
Out of the 163 remaining potential subjects, 156 women could be contacted and recruited for the study after three home-visits (response rate = 95.7%).
We defined persistent, or "specific" responders, as those subjects who had a sustained response at all consecutive visits following the first visit with response, as measured by ≥50% reduction in QIDS-SR scores.
