Analysis of intermediation effects. r: correlation coefficient, *: P < 0.05, **: P < 0.01, ***: P < 0.001。SIRI Systemic Inflammation Response Index, SBP systolic blood pressure, DBP diastolic blood pressure, UAlb urine albumin, UCr urinary creatinine, Cr creatinine, ACR Urine Albumin Creatinine Ratio, eGFR estimated glomerular filtration rate. a Correlation analysis between SIRI, SBP, DBP and kidney function indicators; b Scatter plot of correlation between SBP and DBP as dependent variables and SIRI, eGFR, ACR, Cr, UAlb, UCr; c All mediated effects models had SIRI as the independent variable and systolic and diastolic blood pressure as the mediating variables. Model c1 had eGFR and ACR as dependent variables, model c2 had Cr as dependent variable, model c3 had UCr as dependent variable, and model c4 had UAlb as dependent variable
