Although there is substantial evidence supporting the positive effects of statins for both primary and secondary prevention of these diseases, evidence is lacking regarding the benefits in people with dementia. This study investigated the associations between statin use and cardiovascular and cerebrovascular hospitalizations in nursing home residents with and without dementia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>This retrospective cohort study of nursing home residents with and without dementia using insurance claims data was conducted in Germany between January 2015 and December 2019. Propensity score-based models were used to evaluate the association of statin use with hospitalizations due to cerebrovascular and cardiovascular events among nursing home residents with and without dementia. Subgroup analyses were performed based on the presence or absence of atherosclerotic cardiovascular disease, dementia type, presence of hyperlipidemia, and newly prescribed statin use, as well as age groups, care dependency level, and sex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      The final sample included data from 96\u2009162 individuals, 37\u2009262 without dementia, and 58\u2009900 with dementia.
