Evidence grade: WEAK — Supported only by weak or preliminary evidence.
computed from the encoded evidence by the Atlas grading rule.
Meta-analysis associates T2 high signal (esp. sharp, multisegment) with worse baseline and outcome
Association is inconsistent; signal type matters, quantitative ratios vary, and many patients with T2 change recover well
Influences timing and expectation-setting for surgery; over-weighting T2 signal may deny or delay beneficial surgery.
