Table 5 Calcium and PTH levels post-surgery

	Postoperative day one	Two months post-surgery	Six months post-surgery
Total serum calcium (mmol/L)
Median (range)	2.35 (2.00–2.73) (n = 36)	2.40 (2.18–2.67) (n = 14)	2.41 (2.03–2.83) (n = 12)
Albumin-corrected calcium (mmol/L)
Median (range)	2.37 (2.00–2.75) (n = 34)	2.37 (2.08–2.60) (n = 14)	2.37 (2.10–2.69) (n = 12)
PTH (pmol/L)
Median (range)	2.2 (1.0–5.2) (n = 14)	8.6 (1.2–18.8) (n = 8)	9.9 (1.2–18.8) (n = 7)

Reference range total serum calcium = 2.20–2.60 mmol/L; reference range albumin-corrected calcium = 2.10–2.55 mmol/L; reference range PTH = < 8.7 pmol/L
