The case-control findings revealed a significant association between the presence of a surgical technologist in the operating room during the procedures and the occurrence of NTM infections, indicated by an odds ratio of 55.77 (95% CI [3.16\u2013985.44];\n                      <jats:italic>P<\/jats:italic>\n                      = 0.0097).
