Misclass | Correct | Misclass | Correct | Misclass | Correct | Misclass | Correct | |

Soft | 1.00 | 0 | 0.98 | 0 | 0.86 | 0 | 1.00 | 0 |
Notes: Hard: cutoff probability was set at 0.5. Soft: cutoff probability was equal to the overall mean of the probabilities of being misclassified over the entire data set plus two standard deviations. Misclass: individuals who were misclassified. Correct: correctly coded individuals. The following data sets were simulated: 5% and 0% miscoding rates and moderate OR (D1) or extreme OR (D2); 7 and 3% miscoding rates and moderate OR (D3) or extreme OR (D4).
Abbreviation: OR, odds ratio.
