Calcitriol (mean dose, microgram per day), with or without calcitonin, prevented more bone loss from the lumbar spine (mean rates of change, - and - percent per year, respectively) than calcium alone (- percent per year, P = ). Bone loss at the femoral neck and distal radius was not significantly affected by any treatment. In the second year, lumbar bone loss did not occur in the group previously treated with calcitonin plus calcitriol (+ percent per year), but it did occur in the group given calcium alone (- percent per year). The calcitriol group also lost lumbar bone (- percent per year) but received more corticosteroid in the second year than the other two groups.
