Trial Outcomes & Findings for Anxiolytic and Analgesic Effects of Melatonin (NCT NCT02386319)

NCT ID: NCT02386319

Last Updated: 2021-09-02

Results Overview

The "State" scale of the State-Trait Anxiety Inventory (STAI). Construct: Current level of anxiety. Scale range: 20-40 (higher scores indicate higher level of current anxiety) Scores are calculated according to the STAI scoring manual by adding point from each item (possible point for each item is 1-4).
