Impact of sex on GFR estimation accuracy. Figure 2 shows scatter plots for CIn and other kidney function estimation models dividing into sex. a CIn and CCr, male, b CIn and CCr, female, c CIn and eGFRCr, male, d CIn and eGFRCr, female, e CIn and eGFRCys, male, f CIn and eGFRCys, female, g CIn and eGFRCr+Cys, male, h CIn and eGFRCr+Cys, female, i CIn and eGFR-CKDEPICr, male, j CIn and eGFR-CKDEPICr, female. For reference, auxiliary line which equal to CIn was presented. Abbreviations: GFR glomerular filtration rate; eGFR estimated GFR based on Cr (creatinine) Cys (cystatin C), Cr + Cys (an average of Cr + Cys), or CKDEPICr (a Cr-based equation from The Chronic Kidney Disease Epidemiology Collaboration ([CKD-EPI]); CIn inulin clearance; CCr creatinine clearance
