Which statement is true regarding hormone replacement therapy?

The statement regarding hormone replacement therapy that is true is that some findings may have been affected by socioeconomic status. Research into hormone replacement therapy has shown differing effects based on various factors, including socioeconomic status, which can influence access to healthcare, lifestyle factors, and overall health outcomes. This means that outcomes of hormone replacement therapy can vary significantly across different demographics and should be interpreted with this in mind.

In the context of the other statements, hormone replacement therapy cannot be deemed entirely ineffective, as it has shown benefits for certain individuals, particularly in alleviating menopausal symptoms. It also does not guarantee that there will be no side effects; rather, like any medical intervention, it carries potential risks and side effects which must be considered. Lastly, suggesting that it is universally recommended for all older adults fails to acknowledge the individualized nature of medical treatment, as not everyone may require or benefit from such therapy.
