Effect-site concentration and response curves from the probit analysis in male (○) and female (●) patients. The EC50 and EC95 of remifentanil (95% confidence interval) required to inhibit the CO2 pneumoperitoneum were 4.30 (3.49–4.82) ng/ml and 5.27 (4.78–10.22) ng/ml in women and 5.16 (4.64–5.58) ng/ml and 6.19 (5.70–8.99) ng/ml in men, respectively. CP, CO2 pneumoperitoneum; EC50, median effective concentration; EC95, 95% effective effect-site concentration
