| statistical significance |
Statistical significance is generally interpreted as a result that would occur by chance less than 1 time in 20, with a Pvalue of less than or equal to 0.05. Statistical significance means that the finding is unlikely to be the result of chance. Confidence Intervals show the precision with which the relative risk or odds ratio was measured.
