MO, major outcome; MOA, major outcomes averted. Values in the table are rounded for presentation. QALY, quality adjusted life years; All costs and effects are discounted at 3.5%. Results are presented in rank order of total costs, which include costs of infection, complications, and programme costs. Dominated means that the MOA or QALYs gained is less than the non‐dominated strategy above it in the table.
