Identification of a novel reactive oxygen species (ROS)-related genes model combined with RT-qPCR experiments for prognosis and immunotherapy in gastric cancer.Reactive oxygen species play a crucial role in the prognosis and tumor microenvironment (TME) of malignant tumors.  Finally, we verified the expression of the genes involved in the model using RT-qPCR.
