Evidence-Based Medicine in Otolaryngology Part 15: Introduction to Peer Review-A Framework for Clinicians.

Peer review is an essential cornerstone of scientific advancement. This process involves understanding study design, data analytics, and interpretation of the evidence. For clinicians who are performing their initial peer reviews, and even for seasoned reviewers who assess complex manuscripts, it can be helpful to have a standard approach.

Can EAT-10 Become EAT-5? Improving Measurement Efficiency of Dysphagia with Item Response Theory.

Objectives: To assess: (1) the Eating Assessment Tool (EAT-10) with item response theory (IRT) to determine which individual items provide the most information, (2) the extent to which dysphagia is measured with subsets of items while maintaining precise score estimates, and (3) if 5-item scales have the differing discriminatory ability, as compared to the parent 10-item instrument.

Methods: Prospectively collected data from 2,339 patients who completed the EAT-10 questionnaire during evaluation at a tertiary care otolaryngology clinic were utilized. IRT analyses provided discrimination and location parameters associated with individual questions.

Evidence-Based Medicine in Otolaryngology Part 14: Falsehood and Bias.

Objective: Falsehood and bias can have tangible effects, whether related to the "hoax" of Corona virus disease/COVID-19 or the impact of personal protective equipment in city-wide news. The spread of false information requires the diversion of time and resources into rebolstering the truth. Our objective is thus to elucidate types of bias that may influence our daily work, along with ways to mitigate them.
