From the responses by the nephrologists, the ideal hypothetical patient profile was 50–77 years old (62.5%), CKD stage 4 (47.0%), vitamin D insufficiency (88.5%), persistently high plasma PTH (83.5%), normal serum Ca (48.5%), normal serum P (51.0%), and no history of CV event or fracture (34.0%). Here, PTH is linked to vitamin D deficiency.
