In the cervical myelopathy CPR, the age criterion is greater than which age?

• A. >40 years old
• B. >45 years old
• C. >50 years old
• D. >55 years old

Answer: (B)

The main idea here is how age factors into the cervical myelopathy clinical prediction rule. In this rule, being older increases the likelihood that a patient with neck symptoms has actual cervical myelopathy, because degenerative changes in the cervical spine—and their potential to compress the spinal cord—become more common with advancing age. When researchers developed the CPR, they found that an age cut-off of older than 45 years helped distinguish those with myelopathy from those without, especially when combined with other clinical findings. This threshold was chosen because it offered a useful balance of sensitivity and specificity in predicting cervical myelopathy, helping clinicians decide who should undergo further testing such as MRI. The other age options either capture too broad or too narrow a risk window given the data used to derive the rule, so the threshold of greater than 45 years is the most appropriate reference point within this CPR.
