What is FRAX in osteopenia?

Could you elaborate on the role of FRAX in the context of osteopenia? FRAX, as I understand, is a tool used to assess the risk of osteoporotic fractures. However, I'm curious about its specific application and significance in individuals diagnosed with osteopenia, which is a precursor to osteoporosis. Does FRAX help clinicians determine the likelihood of progression from osteopenia to osteoporosis? Does it factor in additional variables besides bone density measurements to provide a more comprehensive risk assessment? I'd appreciate a concise yet comprehensive explanation of FRAX's role in managing osteopenia.
