In both datasets, obesity was significantly associated with lower odds of high grade compared with non-obese (OR 0.69, 95% CI 0.54-0.88 in Roswell Park, OR 0.62, 95% CI 0.41-0.94 in BUMCT). In Roswell Park, unintentional weight loss at the time of surgery was associated with higher odds of high grade (OR 3.81, 95% CI 2.38-6.09) and advanced stage (OR 4.12, 95% CI 2.74-6.20). In both datasets, older age was associated with reduced odds of obesity and higher odds of high grade, and heterogeneous associations between obesity and high grade by age group were observed (P\n                      <jats:sub>Interaction<\/jats:sub>\n                      = 0.001) in Roswell Park. Former smokers had increased odds of obesity in BUMCT and increased odds of high grade in both datasets. In BUMCT, obesity was significantly associated with reduced odds of high grade in patients who never smoked, not in patients who have smoked, but heterogeneity by smoking status was not significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Higher BMI was linked to a lower likelihood of high-risk RCC pathological characteristics consistent with the obesity paradox.
