These operators intubated 205 patients randomly according to a computer-generated procedure by using either DL or RLGL (five intubations with each technique). The primary outcome was the success rate of tracheal intubation. The authors evaluated the success rate of tracheal intubation, the time to glottic exposure and tracheal intubation, and the Cormack and Lehane grades.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Compared with DL, the success rate was greater in the RLGL group for all five intubations (72%\n                      <jats:italic toggle=\"yes\">vs.<\/jats:italic>\n                      47%; rate difference, 25%; 95% CI [11.84\u201338.16%],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001).
