Three Hour Serum Isotope Estimates Compared to 24-h Urine Fractional Calcium Absorption (FCA) Values. Three-hour serum estimates correlated with 24-h urine FCA in Cohort 1 (ρ = 0.72, p < 0.001, (a) and values were not biased (b). However in Cohort 2, we found no correlation between 3-h serum estimates of FCA and 24-h urine FCA (ρ = 0.03, p = 0.932, (c). Thus, testing of bias via Bland-Altman analysis (d) was not relevant
