Kidney function and shrunken pore syndrome - epidemiological results and methodological issues
Background: Glomerular filtration rate (GFR) is a key indicator of kidney function, typically estimated using creatinine or cystatin C. When cystatin-C-based eGFR is markedly lower than creatinine-based eGFR, this discrepancy may reflect a selective impairment in the filtration of medium-sized molecules, referred to as Shrunken Pore Syndrome (SPS), or more broadly, Selective Glomerular Hypofiltrat
