Cumulative incidence of parathyroid surgery among Rochester, Minnesota residents with definite primary hyperparathyroidism recognized in the prescreening era (1965 to June 1974) versus the postscreening era (July 1974 to 1992) (P = 0.11 for difference between the two curves).

Top panel: survival among Rochester, Minnesota residents with primary hyperparathyroidism in the prescreening era (1965 to June 1974) compared with that expected for Minnesota white residents of similar age and gender (P = 0.71 for difference between observed versus expected survival). Bottom panel: survival among Rochester, Minnesota residents with primary hyperparathyroidism in the postscreening era (July 1974 to 1992) compared with that expected for Minnesota white residents of similar age and gender (P <0.02 for difference between observed versus expected survival).

Survival as a function of quartile of serum calcium levels (I = 10.2 to 10.5 mg/dL; II = 10.6 to 10.7 mg/dL; III = 10.8 to 11.1 mg/dL; and IV = 11.2 to 16.0 mg/dL) among Rochester, Minnesota residents with primary hyperparathyroidism. Group IV had significantly reduced survival (P <0.001) compared with the other 3 groups.

Survival among Rochester, Minnesota residents with definite primary hyperparathyroidism in the highest serum calcium level quartile (11.2 to 16.0 mg/dL) compared with that expected for Minnesota white residents of similar age and gender before parathyroid surgery (A) and following parathyroid surgery (B) (P = 0.91 and 0.41, respectively for difference between observed versus expected survivals).
