The researchers analyzed medical records of more than 100 thousand patients operated by surgeons 3300 in Canada in 2007-2015. They compared the number of deaths after each of the 25 surgical operations carried out by the woman and similar operations carried out by man. Was if the operation was conducted by a woman, the risk of death of the patient was 12% less.

As noted by the authors, it may be that women are more focused on the patient. In addition, they are less likely to take risky decisions and do not hesitate to ask colleagues for help if a problem occurs. The researchers suggest that female doctors put in more effort because they want to prove themselves.
