  1. The number of patients in the screening age range for colorectal cancer screening were calculated from 2016 census data [20]. The percentage of patients eligible for screening and due for screening to return to baseline were determined from the study clinics, then used to estimate the number of patients eligible for screening in Ontario and Canada. The lower confidence level (LCL) and upper confidence level (UCL) were also determined based on the study population. Estimations for Ontario and Canada were rounded to the nearest 1000 patients
