Comparison of demographic, clinical and imaging related variables between patients that were cured postoperatively and the ones with persistent hypercalcemia.

	Cured (n = 7)mean (SD)	Persistence PHPT (n = 5)mean (SD)	P-valuea	Total (n = 12)mean (SD)
Sex (male : female)	2 : 5	0 : 5	0.470	2 : 10
Age at date of operation (years)b	54.1 (16.3)	53.0 (16.1)	0.907	53.7 (15.5)
Preoperative calcium	2.8 (0.1)	2.8 (0.2)	0.945	2.8 (0.2)
Preoperative parathyroid hormonec	18.6 (6.0)	19.8 (4.5)	0.748	19.1 (5.1)
SUVmax (60 minutes)	6.4 (5.4)	3.6 (1.6)	0.300	5.3 (4.4)
SUVmax (90 minutes)	6.1 (4.6)	3.5 (1.6)	0.252	4.9 (3.6)

^a ≤ 0.05 considered significant.

^b Performed after choline scan.

^c Adjusted calcium normal values (2.2–2.6 mmol/l), PTH normal values (1.8–6.8 pmol/l).

PHPT, primary hyperparathyroidism; SD, standard deviation; SUV_max, maximum standardised uptake values.
