CO2 Reactivity as a Biomarker of Non-Response to Exposure-Based Therapy (NCT05467683)
Carbon Dioxide (CO2) Reactivity as a Biomarker of Non-Response to Exposure-Based Therapy
🩺 Plain-English Summary (8th-Grade Level)
Anxiety-, obsessive-compulsive and trauma- and stressor-related disorders reflect a significant public health problem. This study is designed to evaluate the predictive power of a novel biomarker based on a CO2 challenge, thus addressing the central question "can this easy-to-administer assay aid clinicians in deciding whether or not to initiate exposure-based therapy?"
