Status: awaiting_review. Rule: atlas-profile-2.0.
4 linked publications; not a count of independent studies.
Missing appraisal does not mean no evidence exists. Inspect the full profile and source relationships in the interactive Atlas.
Historical grade: WEAK (retained from 22 September 2026; not a completed profile 2.0 assessment).
Morphological grading captures dural-sac deformity better than AP diameter and correlates with symptoms
Grading systems disagree with each other and with surgical findings; interobserver reliability is only moderate and correlation with function is weak
Determines whether imaging grade should drive surgical referral; over-reliance risks operating on radiological rather than clinical severity.
