This implicates covert kidney dysfunction in the pathogenesis of hypertension. I wish to address issues concerning surrogates of clinical disease.The authors excluded participants with overt kidney disease, defined by reduced creatinine level–based estimated glomerular filtration rate (GFR). However the outcome analyses were conducted by using serum cystatin C levels. Would the results materially differ if serum creatinine levels or estimated GFR rates had been ...References1.

Iddo Z. Ben‐Dov (2008) reported a letter. This letter to the editor questions whether the association between kidney function and incident hypertension would materially differ if serum creatinine or estimated GFR were used instead of cystatin C.
