Mediator Variable vs Moderator Variable. There is often confusion among students concerning the difference between a mediator variable and a moderator variable. The explanation involves some concepts that haven't been introduced at this point but it can still be worthwhile to discuss these types of variables.n analysis of variance (ANOVA) terms, a moderator effect can be represented as an interaction between a major independent variable and a factor that specifies the appropriate conditions for its operation, that is, the effect of the major independent variable depends upon the value of the moderator variable.
The most common form of myelopathy in human, cervical spondylotic myelopathy (CSM), is caused by arthritic changes (spondylosis) of the cervical spine, which result in narrowing of the spinal canal (spinal stenosis) ultimately causing compression of the spinal cord.
Myelopathy describes any neurologic deficit related to the spinal cord. When due to trauma, it is known as (acute) spinal cord injury.When inflammatory, it is known as myelitis. Disease that is vascular in nature is known as vascular myelopathy.The most common form of myelopathy in human is caused by degenerative changes in the cervical spine, which cause chronic compression of the spinal cord.Arthritic changes (spondylosis) of the cervical spine results in narrowing of the spinal canal (spinal stenosis) and can cause compression of the spinal cord.isease that is vascular in nature is known as vascular myelopathy.
