Just to be clear, 80 mcg was not the only dose tested. In the earlier studies, they were all tested. There is an increased efficacy with each dose increment. After six months, 80 µg increased bone by 4%. 40 µg, the equivalent of four clicks, increased it by almost 3%. 20 µg by just under 2%. Placebo patients lost a percent as expected.

I'm up to 5 clicks.
