the true population odds ratio may be different than the odds ratio found in the sample. In order to calculate the confidence interval, the alpha, or our level of significance, is specified. An alpha of 0.05 means the confidence interval is 95% (1 – alpha) the true odds ratio of the ...

The same requirements can be summarized in one demand: the odds ratio (OR) must be >= 100. OR = LR+/LR-. Thus, if OR is less than 100 a LR+ = 10 or more will lead to an LR- bigger than 0.1, a LR- smaller than 0.1 will cause LR+ to be smaller than 10....
