This table shows the associations between IMT and individual variables in the subgroups by the eGFR using the same model as model 5 in Table 3. T50, calciprotein crystallization test (serum calcification propensity); eGFR, estimated glomerular filtration rate; CI, confidence interval; CVD, cardiovascular disease; BMI, body mass index; CRP, C−reactive protein; β, standardized regression coefficient; R2, coefficient of determination for the model.
