Effect of Clot Composition on Experimental Outcome. Cumulative incidence values and a rate ratio were calculated to determine whether a change in the clot composition has an effect on the experimental outcome.
| Groups | Unsuccessful | Successful | Total | Cumulative Incidence |
|---|---|---|---|---|
| Hard Clot | 9 | 0 | 9 | 9/9 = 100% |
| Soft Clot | 14 | 18 | 32 | 14/32 = 43.75% |
Rate Ratio = 100/43.75 = 2.29
