BROS (V : R): best ratio of synergy (vecuronium : rocuronium), EC50,V and EC50,R: median effect of vecuronium and rocuronium, respectively, γV and γR : Hill slope of vecuronium and rocuronium, PD Pmt: pharmacodynamic parameter, RS: response surface, Kong and Plummer: assume that relative potency ratio is constant (or the dose-effect curves are parallel).
