Quality of reporting of otorhinolaryngology articles using animal models with the ARRIVE statement

Research involving animal models is crucial for the advancement of science, provided that experiments are designed, performed, interpreted, and reported well. In order to investigate the quality of reporting of articles in otorhinolaryngology research using animal models, a PubMed database search was conducted to retrieve eligible articles. The checklist of the ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines was used to assess the quality of reporting of articles published in ear, nose and throat (ENT) and multidisciplinary journals. Two authors screened titles, abstracts, and full texts to select articles reporting otorhinolaryngology research using in vivo animal models. ENT journals (n = 35) reported a mean of 57.1% adequately scored ARRIVE items (median: 58.3%; 95% confidence interval [CI; 53.4–60.9%]), while articles published in multidisciplinary journals (n = 36) reported a mean of 49.1% adequately scored items (median: 50.0; 95% CI [46.2–52.0%]). Articles published in ENT journals showed better quality of reporting of animal studies based on the ARRIVE guidelines (P
