Figure 4.

A. Forest plot of comparison of urine calcium between juvenile PHPT and adult PHPT. Urine calcium in pediatric PHPT is significantly increased relative to adult PHPT, P < .05 (paired t test with Welch's correction for unequal variances); pediatric mean, 9.95 mmol/d (95% CI, 7.4–12.7) vs 7.15 mmol/d (95% CI, 6.03–8.24). Summary or individual statistics for urinary calcium were reported for 264 subjects. B. Forest plot of comparison of gland size between juvenile PHPT and adult PHPT. Differences between groups are not statistically significant, P = .12, (paired t test with Welch's correction for unequal variances); mean mass for pediatric gland, 2021 mg (95% CI, 1246–2797), vs mean mass for adult gland, 1188 mg (95% CI, 472–1905).
