Negative | 39 (37.46)^{*} | 7 (8.54) | 46 |

* Numbers in parentheses are calculated.

Note: The observed χ

^{2}= 0.99. If there were an effect at the*P*= .25 level, then the expected χ^{2}= 1.32; and at the*P*= .05 level, the expected χ^{2}= 3.841. Because the observed does not exceed the expected, the type of margin does not affect the frequency of no recurrence (*P*> .25). Accept the null hypothesis that the frequencies are the same.
