Postmenopausal Hormone Replacement Therapy and the Primary Prevention of Cardiovascular Disease

Figure 4. Error bars represent 95% CIs. HRT = hormone replacement therapy; RCT = randomized, controlled trial; SES = socioeconomic
status. “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). Adjustments for SES were adjustments as assessed by social class , education
, and income.
