Table 1.
Probability of Detecting Effects Based on Cohort Size.
Cohort Size (Individual Cell lines) (N) | 1 in 10 (Decile) Population Incidence (%) | 1 in 4 (Quartile) Population Incidence (%) |
---|---|---|
24 | 92 | 99.9 |
16 | 81.5 | 99.0 |
4 | 34.4 | 68.3 |
The table provides exact probabilities for common population incidence frequencies and cohort sizes. Monte Carlo simulations were performed assuming a normal distribution of drug toxicity or sensitivity.
