In any particular case the true odds ratio may lie anywhere within the interval, or it might not be contained within it, no matter how high the confidence level is. But I'm not clear on what to do when the odds ratio is more than 1.0, like 4.37 or 3.09. If the test was two-sided, you need to multiple the p-value by 2 to get the two-sided p-value.
