After excluding one incomplete response, data from 4799 participants were analysed. Participants were grouped by ED severity according to IIEF\u20105 score. The total and subcategory scores of the IPSS and OABSS were compared among the groups. LUTSs were categorized as post\u2010micturition, storage, voiding symptoms and incontinence. An additional analysis was conducted by age group: younger (40s\u201350s) and older (\u226570s).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Lower ED severity was associated with significantly lower IPSS and OABSS total scores (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

Severe ED (IIEF\u20105 to &lt;8) was significantly associated with worse scores across all the LUTS domains.
