Mean (±SEM) ethanol-appropriate responding and percentage of baseline response rate (RR) by test drug dose in female sham (closed circles) and ovariectomized (open circles) rats trained to discriminate 1.0 g/kg ethanol from water. The dashed lines show the criteria for complete substitution and response rate equivalent to baseline. On average, each rat was tested with a (mean±SD) minimum of 5.5±1.5 doses and a maximum of 12.1±1.8 doses of each drug; **P<0.01. i.p. intraperitoneally.
