Laboratory results at baseline and follow-up. a Laboratory values of serum PTH (pg/mL), calcium (Ca, mg/dL), and phosphate (P, mg/dL) in the SHPT/CKD-HD and PTH population at baseline (green), 6-month follow-up (orange), and 12-month follow-up (pink). The median is represented by a line within the colored boxes, enclosed by Q1 at the bottom and Q3 at the top. b Percentage of patients with normal levels of PTH (150–450 pg/mL), calcium (Ca, 8.4–9.4 mg/dL), and phosphate (P, 2.5–4.5 mg/dL) in green, and values outside normal ranges at baseline, 6-month follow-up, and 12-month follow-up (in yellow and red). See online supplementary Table S3 for complete data analysis.
