Why the study?
Practice patterns differ between female and male physicians, but the influence of physician sex on team-based operating room practices and patient outcomes after noncardiac surgery remains unclear.

Sex-discordant teams should not yet alter assignment practices; leaves open whether discordance causally affects noncardiac surgery mortality.
Does surgeon-anesthesiologist sex discordance reduce 1-year mortality in adults undergoing noncardiac surgery?
Patients undergoing noncardiac surgery have a lower likelihood of 1-year mortality when treated by sex-discordant surgeon-anesthesiologist teams, particularly when the surgeon is female.
