Combined EGCG and cisplatin treatment in BTC cell lines. Potential synergistic cytotoxic effects of combined EGCG and cisplatin treatment were evaluated in eight BTC cell lines. Cell viability is represented relative to untreated control. For SkChA-1 cells, values from single treatments were suitable for CI calculation. Single treatments, as well as drug combinations are indicated as “+”. Based on [27], the CI was calculated: a CI less than 0.9 represents a synergistic, a CI greater than 1.1 an antagonistic and a CI between 0.9 and 1.1 an additive effect. CI values are shown within the bars of the drug combinations. Abbreviations: BTC: Biliary tract cancer, CI: combination index, EGCG: Epigallocatechin gallate
