Open the original (DOI 10.1038/s41598-026-36500-7)- What it measures
- An intraclass correlation near 1 means a person's score stays about the same from one test to the next.
- What it does not show
- Two measurements over two years in one panel. It says the test measures something stable, not what that thing is.
