Dear Editor,

The question raised in the Letter to the Editor is justified, and we completely agree with the authors.

So, it is better to correct conclusions in abstract on page 2 as follows:


Conclusions: Increasing severity of SedSign indicates progressively smaller dural sac CSA, but there is an inconsistent association with clinical symptoms. Therefore, it is reasonable to suggest that spinal stenosis is severe in patients with severe symptoms.
