Adjusted odds of a patient having been referred to a nephrologist by a specialist in relation to serum creatinine (A) and eGFR (CKD-Epi), (B) during the study visit.

<p>Models were adjusted for age, gender, race, presence of diabetic renal disease, center, systolic and diastolic blood pressure and time the patient had been under nephrology care. Solid black line: estimated adjusted odds ratio, dashed black lines: associated pointwise 95% confidence internal, gray horizontal line: corresponds to an odds ratio of one.</p
