a1 and a2: CALCBD levels at different time points and at different heights of the radius. a1: Measurements at − 4% of the total length of the radius on the healthy side. Measurements were taken after zero and 6 weeks. The isolated points represent two outliers. a2: Shows the measurements at 6 weeks after removal of the external fixateur and the k-wires on the fractured side (n (E2) = 31; n (placebo) = 45). b1 and b2: CORTBD density levels at different time points and at different heights of the radius. b1: Measurements at − 4% of the total length of the radius on the healthy side. Measurements were taken after zero and 6 weeks. b2: Shows the measurements at 6 weeks after removal of the external fixateur and the k-wires on the fractured side (n (E2) = 31; n (placebo) = 45). The isolated points represent three outliers. c1 and c2: CALCBD area levels at different time points and at different heights of the radius. c1: Measurements at − 4% of the total length of the radius on the healthy side. Measurements were taken after zero and 6 weeks. The isolated points represent three outliers. c2: Shows the measurements at 6 weeks after removal of the external fixateur and the k-wires on the fractured side (n (E2) = 31; n (placebo) = 45). The isolated point represents an outlier. Median values are shown
