Primes¶
- Potentiation
- As Chou and Talalay (1984) formalize through their median-effect equation and combination index, the dose-response curve shifts leftward—meaning a given response is evoked at lower drug concentration or stimulus intensity (reduced ED₅₀)—or the maximal achievable response increases (elevated E_max), or both.
This sourceCombination-index method based on the median-effect equation; provides the statistical machinery for distinguishing synergy from antagonism with replicated dose ratios, addressing the sample-size and false-positive concerns of underpowered interaction studies.

- Synergy and Antagonism
- Failure mode: interaction effects are claimed from studies powered only for main effects, producing false-positive synergy or antagonism claims — a methodological hazard the combination-index framework of Chou and Talalay (1984) was specifically designed to discipline through median-effect analysis and replicated dose ratios.
