  1. aRace data is available for 42,396 patients
  2. bDefined as the percentage of the population with a high school diploma in a specific patient’s area code
  3. cDefined based on the number of regional lymph nodes sampled during surgery. Yes = 1+; No = 0
  4. dSurgical volume groups were identified based on quartile rank of the total number of endometrial cancer patients undergoing surgery and the total number of years of reported data: 75th percentile = very-high volume (>31.7cases/year); 51st–75th percentile = moderately-high volume (13.3–31.6 cases/year); 25th–50th percentile = intermediate volume (6.7–13.2 cases/year); and <25th percentile = low volume (<6.7 cases/year)
