Race, ethnicity, and BMI cohorts consisted of 18- to 44-year-old female patients with diagnoses of endometriosis (ICD-10 N80) and pelvic\u2013perineal pain (ICD-10 R10.2). Age cohorts consisted of female patients aged 18\u201330 years or 31\u201344 years, with the same two diagnoses. The BMI cohorts were categorized as lower than 19.9 (ICD-10 Z68.1), 20\u201329 (ICD-10 Z68.2), and higher than 30 (ICD-10 Z68.3, Z68.4). Patients were matched for race, ethnicity, and age at pelvic pain diagnosis. We assessed time to endometriosis diagnosis after an initial diagnosis of pelvic and perineal pain using Kaplan\u2013Meier analysis and log-rank test with a value of\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;.05 considered significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      For patients aged 18\u201330 years (n=13,662), the median time to endometriosis diagnosis was 0.49 years; for patients aged 31\u201344 years (n=13,662), the median time to diagnosis was 3.10 years (\u03c7\n                      <jats:sup>2<\/jats:sup>\n                      =3,503,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;.001).
