Cytotoxicity and synergy scores of the combination of abemaciclib and altiratinib in two GIC lines calculated with the Bliss method. Increasing doses of each agent provided higher cytotoxicity and better Bliss difference (first number shown is observed cell death; second number is observed cell death minus expected death=Bliss difference).
