ED and PE severity were assessed using the IIEF-5 and CIPE. Patients were classified as PE only (\n                      <jats:italic>n<\/jats:italic>\n                      = 120), ED only (\n                      <jats:italic>n<\/jats:italic>\n                      = 72), or comorbid ED-PE (\n                      <jats:italic>n<\/jats:italic>\n                      = 38). The McNemar test was used to evaluate asymmetry in comorbidity distribution, and comparisons were made across ED severity grades.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The prevalence of PE (68.7%) was higher than that of ED (47.8%). There was significant asymmetry: PE alone (\n                      <jats:italic>n<\/jats:italic>\n                      = 120) was more common than ED alone (\n                      <jats:italic>n<\/jats:italic>\n                      = 72); (\n                      <jats:italic>P<\/jats:italic>\n                      = 0.0007). ED severity showed a unidirectional association with PE risk; comorbidity rates increased from mild to moderate ED (22.2% \u2192 42.9%) but plateaued thereafter (severe ED 43.3%). Severe ED had a higher PE risk than mild ED (RR = 1.95,\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.05).

Because of the cross-sectional design, these findings are preliminary and should be interpreted as associations rather than causal relationships. Prospective studies are needed to determine whether early ED progression is a critical risk window for PE. The mild-to-moderate ED group, representing a larger target population with the most pronounced risk escalation, warrants further investigation in future studies.<\/jats:p>\n
