Inclusion criteria focused on anemia in the elderly, reporting prevalence, etiology, or outcomes. Quality was assessed using the Newcastle-Ottawa Scale and AMSTAR 2. Narrative synthesis, supported by biostatistical analyses (pooled prevalence, hazard ratios [HRs], odds ratios, 95% confidence intervals [CIs]), was performed, with heterogeneity assessed via I\u00b2 statistics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Anemia prevalence ranged from 10% to 50% (pooled prevalence 27.8%, 95% CI: 22.1\u201333.5, I\u00b2 =92%), higher in hospitalized patients (37.4%, 95% CI: 29.8\u201345.0) than community-dwelling elderly (23.1%, 95% CI: 18.2\u201328.0).
