From my limited understanding, HDL quantity seems to have a "J" shaped benefit distribution. Beware of the J shape. Often J-shaped curves for health outcomes are seen when measurements are taken at one point in time, and the apparent 'optimal' level turns out to be very different from the...

In this study the researchers took advantage of the fact that there was a sharp cut-off for eligibility for the vaccin...

And I am in osteoporosis now, so I'm really in need of a solu...
