Expected versus observed number of mutations by risk.* Values are numbers (percentages)
| Model | Number of families | Observed | Expected | Observed/expected | χ2 |
|---|---|---|---|---|---|
| *Probabilities stratified in three groups separately by model, so that families in each group differ across models. | |||||
