Likelihood, Nomogram, Cozen test, lateral epicondylitis



The purpose of this study was to determine the prevalence of lateral epicondylitis among recreational athletes of Karachi population, as well as checking the validity of self-designed questionnaire using likelihood ratio. This was a cross sectional study, including 193 participants (176 males and 17 females) from different clubs of karachi districts. A self-designed questionnaire was used to take pre assessment measure of lateral epicondylitis. After the completion of questionnaire, Cozen test was applied on each participant. The results obtained from the scoring of the questionnaire and cozens test were compared using the likelihood ratio, proceeded by the comparison of the pretest and posttest probability. 7 out of 193 were found to have a positive test. The results revealed that the prevalence of LE among young recreational athletes (aged 20-40 years) was estimated to be 3.6%, whereas, the questionnaire used has a sensitivity of 10.5%, and the specificity of 97%. Thus, this confirms that the questionnaire used, is valid to rule in the negative results.
