  1. Values are expressed as frequency.
  2. Both the incidence and severity of cough in patients in Group R were significantly lower compared to those in patients in Group C (P < 0.01).
  3. R = remifentanil; C = control. The severity of cough was graded as mild (1, 2), moderate (2, 3), or severe (> 5) based on the number of cough observed in 60s after sufentanil injection. *Indicates P < 0.01 compared with patients in Group C.
