Table 1. Hypocalcaemia outcomes in relation to the extent and sequencing of thyroid resection.

Outcome	First-time			Re-operative: total thyroidectomy (n=266)	Sum of affected patients (all groups)
	Total thyroidectomy (n=8,672)	Lobectomy with contralateral sub/near-total lobectomy (n=191)	Bilateral sub/near-total lobectomy (n=277)
Hypocalcaemia during index admission	23.6 (22.7–24.5)	15.2 (9.9–20.5)	22.8 (17.8–27.8)	24.6 (19.3–30.7)	2,196
Treatment with Ca2+/Vit D at discharge	37.9 (36.9–39.0)	30.7 (23.7–37.7)	28.6 (22.8–34.4)	40.0 (33.6–46.4)	3,362
Treatment with Ca2+/Vit D at 6 months post-op	7.3 (6.7–7.9)	4.8 (1.6–8.0)	5.5 (2.6–8.4)	10.8 (6.5–15.0)	606

Results are % of the respective cohort (excluding cases with missing data for the relevant outcome) + 95% confidence intervals.
