Specifically, in the instructions for authors, Manuscript Formatting and Submission Requirements, section 2.4.2.2 Structured abstract and keywords, it reads “Reporting of odds ratios is discouraged (marginal effects preferred) except in case-control studies” (see the &lt;i&gt;HSR&lt;/i&gt; website https://www.hsr.org/authors/manuscript-formatting-submission-requirements).&lt;/p&gt;&lt;p&gt;We applaud this decision. We also encourage other journals to make the same decision. It is time to end the reporting of odds ratios in the scientific literature for most research studies, except for case–control studies with matched samples.&lt;/p&gt;&lt;p&gt;&lt;i&gt;HSR&lt;/i&gt;'s decision is due to increasing recognition that odds ratios are not only confusing to non-researchers,&lt;span&gt;&lt;sup&gt;1, 2&lt;/sup&gt;&lt;/span&gt; but that researchers themselves often misinterpret them.&lt;span&gt;&lt;sup&gt;3, 4&lt;/sup&gt;&lt;/span&gt; Odds ratios are also of limited utility in meta-analyses. Marginal effects, which represent the difference in the probability of a binary outcome between comparison groups, are more straightforward to interpret and compare. Below, we illustrate the difficulties in interpreting odds ratios, outline the conditions that must be met for odds ratios to be compared directly, and explain how marginal effects overcome these difficulties.&lt;/p&gt;&lt;p&gt;Consider a hypothetical prospective cohort study of whether a new hospital-based discharge program affects the 30-day readmission rate, a binary outcome, observed for each patient who is discharged alive. The program's goal is to help eligible patients avoid unnecessary readmissions, and patients are randomized into participating in the program or not. Suppose that a carefully designed study estimates the logistic regression coefficient (the log odds) on the discharge program to be &lt;span&gt;&lt;/span&gt;&lt;math&gt;\u0000 &lt;mrow&gt;\u0000 &lt;mo&gt;−&lt;/mo&gt;\u0000 &lt;mn&gt;0.2&lt;/mn&gt;\u0000 &lt;/mrow&gt;&lt;/math&gt;, indicating that readmission rates are lower for patients who participate in the discharge program than patients who do not. When writing about the results, the researcher must decide how to report the magnitude of the change and has several choices for how to do so.&lt;/p&gt;&lt;p&gt;One option is to report the odds ratio, which in this case is &lt;span&gt;&lt;/span&gt;&lt;math&gt;\u0000 &lt;mrow&gt;\u0000 &lt;mn&gt;0.82&lt;/mn&gt;\u0000 &lt;mo&gt;=&lt;/mo&gt;\u0000 &lt;mi&gt;exp&lt;/mi&gt;\u0000 &lt;mfenced&gt;\u0000 &lt;mrow&gt;\u0000 &lt;mo&gt;−&lt;/mo&gt;\u0000 &lt;mn&gt;0.2&lt;/mn&gt;\u0000 &lt;/mrow&gt;\u0000 &lt;/mfenced&gt;\u0000 &lt;/mrow&gt;&lt;/math&gt;, and then compare it with other published odds ratios in the literature. However, this estimated odds ratio of 0.82 depends on an unobservable scaling factor that makes its interpretation conditional on the data and on the model specification.&lt;span&gt;&lt;sup&gt;3, 5","PeriodicalId":55065,"journal":{"name":"Health Services Research","volume":"59 4","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1475-6773.14337","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141187228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
