The total number of patients in the study was 370, but only 346 had information regarding body mass index.
The authors also included an age-adjusted model. The hazard ratios (HR) and confidence intervals (CI) were 1.19 (0.78–1.83), 1.43(0.92–2.22), and 1.86 (1.20–2.88) for women with BMI 25–30, 30–35, and >35 compared to BMI < 25, respectively (p = 0.004).
Geographic settings included California, Florida, Pennsylvania, New York, North Carolina, Arizona, Massachusetts, Washington D.C., Ohio, and Iowa.
Data presented was determined using a multivariate model adjusting for grade, stage, chemotherapy; and surgery. The authors also included a second model adjusting for grade, stage, race, chemotherapy, surgery, smoking, diabetes, and family history of breast cancer. Using this model the hazard ratios (HR) and confidence intervals (CI) were 1.74 (1.13–2.66), 1.84(1.17–2.88), and 2.35 (1.48–3.73) for women with BMI 25–30, 30–35, and >35 compared to BMI < 25, respectively (p < 0.001).
Geographic settings included California, Florida, Pennsylvania, New Jersey, North Carolina, Louisiana, Georgia, Michigan, Texas, Arizona and Nevada.

The data represents survival outcomes for women with Type I endometrial cancer. The authors also included a separate analysis for women with Type II endometrial cancers. The hazard ratios (HR) and confidence intervals (CI) were 0.96 (0.46–2.02), 0.76 (0.31–1.87), and 0.88 (0.33–2.35) for women with BMI 25–29.9, 30–34.9, and 35.0–39.9 compared to BMI 8.5–24.9, respectively (p = 0.664).
Geographic setting: Georgia.
Only data from the adjusted analysis is listed.
BMI was only evaluated as a continuous variable.
