AI Article Synopsis
- The study evaluates the levels of evidence (LOE) in references from three clinical chapters of a dental textbook across five editions, focusing on their educational value.
- Out of 3656 references analyzed, more than 60% were categorized as LOE 0 (no evidence), indicating a significant gap in quality evidence in the chapters on Trauma, Re-treatment, and Surgery.
- The findings suggest that while some chapters showed variation in evidence quality over editions, overall, low-level evidence predominates, highlighting the need for policies to encourage higher-quality research in dental education.
Article Abstract
Introduction: The levels of evidence (LOE) of dental education texts is critical from the educational point of view. The present study aimed to evaluate the levels of evidence of references used in three clinical chapters in the textbook .
Material & Method: The references of three clinical chapters in the text book were assessed in five of its editions. The levels of evidence were ranked according to study type and the Oxford scale from 0 to 5. The chi-square test was used to compare the level of evidence between different editions of the "Retreatment," "Trauma," and "Surgery" chapters.
Results: A total of 3656 references were reviewed and analyzed from the "Trauma" (928 references), "Re-treatment" (1906 references), and "Surgery" (822 references) chapters in the 1998, 2002, 2006, 2011, and 2016 editions. The percentage of the LOE 0 (no evidence) was high (>60%) in all three chapters in all editions (<0.001). The levels of evidence had the same distribution in all editions (=0.871). The LOE of the "Re-treatment" (=0.044) and "Surgery" (<0.001) chapters changed in some editions.
Conclusion: The majority of references in the three clinical chapters of the book are low-level evidence. Encouragement policies for researchers to conduct studies with high LOE are necessary.

Section of Young Adult Hip Surgery, Division of Sports Medicine, Department of Orthopedic Surgery, Rush University Medical Center, Chicago, Illinois, USA.
Background: Many studies have examined the prevalence of acetabular version (AV) and femoral version (FV) abnormalities and their effect on patient-reported outcomes (PROs) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS), but few have explored the prevalence and influence of combined version (CV) abnormalities.
Purpose: To (1) describe the distribution of AV, FV, and CV in the largest cohort to date and (2) determine the relationship between AV, FV, and CV and PROs after hip arthroscopy for FAIS.
Study Design: Cohort study; Level of evidence, 3.
Athlete Selective Androgen Receptor Modulators Abuse: A Systematic Review.
Am J Sports Med
January 2025
Case Western Reserve University School of Medicine, Cleveland, Ohio, USA.
Background: Selective androgen receptor modulators (SARMs) are small-molecule compounds that exert agonist and antagonist effects on androgen receptors in a tissue-specific fashion. Because of their performance-enhancing implications, SARMs are increasingly abused by athletes. To date, SARMs have no Food and Drug Administration approved use, and recent case reports associate the use of SARMs with deleterious effects such as drug-induced liver injury, myocarditis, and tendon rupture.
