eGFR in CSF-flow disorders - a representation of comorbid state or an element of the underlying pathophysiology?

All cause mortality increases with lower levels of estimated glomerular filtration rates. As part of a comorbidity focus, we assessed the eGFR in CSF-flow disorder patients guided by NICE recommendations, current literature recognising a relative hazard ratio per 15mls/min decrease in eGFR of 1.04[1] and consideration of the 2010 Chronic Kidney Disease Epidemiology Collaboration eGFR categories.
