Ann Med Surg (Lond) 2019; 44:102-103. [PMID: 31388416 PMCID: PMC6667739 DOI: 10.1016/j.amsu.2019.05.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2019] [Revised: 05/17/2019] [Accepted: 05/27/2019] [Indexed: 11/30/2022] Open
Abstract
It is good to know that sensitivity is an important measure in public health aspects instead of clinical fields. Likewise, PPV and NPV are among the measures which are more appropriate for advice about the validity of a diagnostic test for clinical purposes. It is critically important to consider that accurate diagnosis is very important in appendicitis because of the urgent need for surgery in people who are truly positive, likewise, operating surgery for people who are not truly positive will have inconvenient effects. Finally, for the prediction of an outcome, we need data from two different cohorts or at least from one cohort divided into two to first to develop a prediction model and subsequently validate it. To make our methodological comments brief, it is crucial to know that to determine the validity and predictive ability of ultrasound in predicting acute appendicitis among children, methodological and statistical issues should be correctly taken into account.

Abstract
Reliability (precision, repeatability, agreement) and validity (accuracy) are two completely different issues which should be assessed using appropriate tests. It is crucial to know that, reporting concordance rate; the selection error rate and the classification error rate are not the most appropriate estimates to assess reliability. Regarding reliability, for qualitative variables, weighted kappa should be used with caution. However, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), likelihood ratio positive and negative as well as diagnostic accuracy are estimates that are usually used to evaluate the validity of a test compared to a gold standard.
