The combined treatment was performed at the indicated fixed 1:1 ratio relative to their respective IC50 concentrations. CI values were calculated for each constant ratio combination and at effect levels ED50, ED75 and ED90 from the average of at least three independent experiments. CI values (<1.0) are highlighted in bold font. CI, combination index; ED, median effective dose.
