{"denomUnitsSelected":"Participants","description":"Each of the NCORP components (we anticipate 25 NCORP components) will each need to enroll, on average, about 5 patients per year. Accrual will be assessed at 1.5 years after study activation. If monthly average accrual in quarters 5-6 after study registration is \\< 50% of projected accrual, efforts will be made to increase accrual over the succeeding 6 month period. If after 2 years, monthly accrual remains \\< 50% of projected accrual, study revision will be considered. In order to address the potential for selection bias, demographics (age, race, gender, etc.) of the final cohort will be compared","reportingStatus":"NOT_POSTED","timeFrame":"Up to 3 years","title":"Accrual to a Prospective-multi-site Longitudinal Cohort Study","type":"SECONDARY"}
