Reducing Systematic Overestimation Bias in the Duke Activity Status Index Estimated Peak Oxygen Uptake: A Cross-Sectional Analysis Using Submaximal Cardiopulmonary Exercise Testing
Hollingsworth K, Zhao Y, Charchaflieh J, Carr Z. Reducing Systematic Overestimation Bias in the Duke Activity Status Index Estimated Peak Oxygen Uptake: A Cross-Sectional Analysis Using Submaximal Cardiopulmonary Exercise Testing. A&A Practice 2026, 20: e02160. PMID: 41729842, DOI: 10.1213/xaa.0000000000002160.Peer-Reviewed Original ResearchThis study addresses the systematic overestimation of peak oxygen uptake by the Duke Activity Status Index (DASI) by validating a new, adjusted formula. By integrating BMI, age, and sex into the formula, the authors reduced bias.Does a Research Paper Always Need a Hypothesis?
