Though the “evidential” meaning of <i>P</i>-values is contested and generally dubious,<span><sup>3</sup></span> in simple terms the <i>P</i>-value can be considered a summary of the evidence provided by the data to <i>refute</i> the test hypothesis,<span><sup>4</sup></span> or equivalently, an expression of how surprising it would be to observe data at least as extreme as these, if the test hypothesis was in fact true.<span><sup>2</sup></span> Though a small <i>P</i>-value may suggest (charitably) that some aspect of the test hypothesis is untrue, the usage advocated by Fisher, a large <i>P</i>-value does not support that it is true, because it says nothing about other test hypotheses (in this case, difference between interventions) with which the data may be compatible. It is, therefore, incorrect to conclude anything substantive from a large <i>P</i>-value. Unfortunately, the incorrect interpretation that a large <i>P</i>-value indicates that an effect or association is absent appears common in clinical trials reporting.<span><sup>5</sup></span></p><p>An emphasis on confidence intervals may mitigate some of the limitations of reasoning based on hypothesis tests, even if their exact meaning is unintuitive. This is a popular view,<span><sup>6</sup></span> and is generally encouraged by relevant reporting guidelines.

On serology <i>Leptospira interrogans</i> serovar Australis, Autumnalis, and Bratislava accounted for 86% of all titers ≥1 : 800. Overall case fatality rate was 4/11 (36%). Main findings on necropsy were tubular necrosis, interstitial nephritis, hemorrhage in the alveoli, pulmonary edema, periportal hepatitis and necrosis, cholestasis, and cholangitis.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions and Clinical Importance</h3>\u0000 \u0000 <p>Leptospirosis should be considered as a differential diagnosis in horses with evidence of acute systemic inflammation and acute renal injury, epistaxis, or hepatic disease.

Therefore, 11 electrodes were placed encircling the thorax behind the olecranon, to construct triangles with a horizontal base. Electrocardiogram recordings from different triangles were analyzed. Signal processing involved filtering, R peak detection, and median complex generation.

Because the Delta configuration is positioned in the transverse plane, it forms the ideal basis for 12-lead ECG recordings that provide vectorcardiograms in an orthogonal coordinate system. Standardizing electrode positioning could improve ECG data comparability in equine cardiology.</p>\u0000 </section>\u0000 </div>","PeriodicalId":49958,"journal":{"name":"Journal of Veterinary Internal Medicine","volume":"38 5","pages":"2698-2706"},"PeriodicalIF":2.1,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jvim.17179","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142080643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
