two-way sensitivity analysis of American Markov model in China (A) and in the United States (B). X-axis: Variation in the first parameter (e.g., drug cost or effectiveness). Y-axis: Variation in the second parameter (e.g., utility values or transition probabilities). Color Gradient: Represents the resulting ICER values (The blue area signifies that the olaparib strategy is more cost-effective, while the red area suggests that the placebo strategy is more cost-effective).The blue area signifies that the olaparib strategy is more cost-effective, while the red area suggests that the placebo strategy is more cost-effective
