Graham 2006 CTS-6 from six caller-assigned booleans with published discrete weig
Graham 2006 CTS-6 from six caller-assigned booleans with published discrete weights (median-territory numbness 3.5, nocturnal numbness 4, thenar atrophy or weakness 5, Phalen 5, two-point discrimination loss 4.5, Tinel 4; max 26). Score >5 is associated with ≈25% probability of CTS; score >12 with ≈80%. magent does not examine the patient. Deterministic published arithmetic with citation; not a CTS diagnosis, not an EMG order, not a Boston questionnaire, and not a medical device.
