HRT = hormone replacement therapy. "Current," "past," and "ever" use are categories used in the individual studies. "Any use" is a category created for this meta-analysis combining data from studies evaluating ever and never use of HRT with data from studies evaluating current, past, or never use (current + past + ever use).
