Achievement of a ≥ 30% Reduction in Mean PTH From Baseline to During the Efficacy Assessment Phase at Month 6 (Weeks 22 to 26) Primary · Weeks 22-26

All available measurements from the efficacy assessment phase (EAP) at month 6 were used in the calculation of the mean over the period. For participants with no measurements taken during the EAP, the mean of the last 2 measurements available after Day 1 were carried forward. If there was only 1 value available, this single value was carried forward to the EAP.
