Figure 1. sTNF-R1 and change in eGFR/creatinine from baseline to follow-up.
Black line: regression line with corresponding 95% (dashed line); vertical blue line: optimal cut off; black dots: subjects with eGFR<60 mL/min/1.73 m2 at follow-up; grey dots: subjects with eGFR>60 mil/min at follow-up. Abbreviations: sTNF-R1: Soluble tumour necrosis factor-α receptor 1, eGFR: estimated glomerular filtration rate.
