Figure 2. Decline of cyclase activating parathyroid hormone (CAP), intact parathyroid hormone (iPTH), and 7-84 parathyroid hormone (PTH) after excision of one enlarged parathyroid gland in the 29 patients with primary hyperparathyroidism. Results are shown as the percentage of the higher value of either basal or preexcision and means (standard error). There were significant differences in the percentage decrease among them (P = .0001) by a generalized linear regression analysis. CAP was significantly lower than iPTH at all times (P = .0001) by analysis of variance. The 7-84 PTH level was calculated by subtracting the CAP value from the iPTH value.
