Effect of image quality on diagnostic accuracy of noninvasive fractional flow reserve: Results from the prospective multicenter international DISCOVER-FLOW study
Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Canadian affiliationAn author listed a Canadian institution. This is the only route the usual frame has.

Claude Opus 4.8OUT
genre: empirical
about Canada: no
confidence: high
Diagnostic accuracy substudy of noninvasive fractional flow reserve by image quality; a clinical test-performance question, not a study of research practice.
GPT-5.6 (high)OUT
genre: empirical
about Canada: no
confidence: low
The title indicates a clinical diagnostic-accuracy study, but the abstract is missing.

genre: empirical
about Canada: no
confidence: medium
Clinical study of CT image quality versus diagnostic accuracy of noninvasive FFR; polysemy of quality.
Abstract
No abstract. This is not a gap in this database — OpenAlex has none either. 23.3% of the frame is in this state, and the screen finds HALF as much metaresearch here, so the absence is a measured bias rather than a missing field.
