Table 5:

Effect of Clot Location within Device on Experimental Outcome. Cumulative incidence values and rate ratios were calculated to determine whether a change in the clot location within the device has an effect on the experimental outcome.

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
