A significantly high correlation between whole-PTH and intact-PTH was observed in the patient population as a whole ( r = 0.975, y = −12.0 + 0.699 x ), as well as in each group; however, the slope of each group showed a trend to increase in association with the severity of hyperparathyroidism (low group, 0.637; moderate group, 0.673; high group, 0.737).
