Table 5:
Groups | Unsuccessful | Successful | Total | Cumulative Incidence |
---|---|---|---|---|
Mid | 16 | 8 | 24 | 16/24 = 66.66% |
Proximal | 6 | 9 | 15 | 2/4 = 50% |
Distal | 1 | 1 | 2 | 1/2 = 50% |
Rate Ratio (Mid/Proximal) = 66.66/50 = 1.33
Rate Ratio (Mid/Distal) = 66.66/50 = 1.33
Rate Ratio (Proximal/Distal) = 50/50 = 1.00
