The calculation was based on being able to identify a 10% (absolute) difference in the frequency of occurrence of a risk factor in a group of 244 tackle injuries (the sample population available in this study) compared with a 30% frequency of occurrence in the general play group with 90% power and 95% confidence.document.currentScript.parentNode.insertBefore(s, document.currentScript);Tadalafil No Rx.
