Tornado analysis of expected QALYs per worker over 20 years: 3% discount rate. TB tuberculosis, HCWs healthcare workers, LTBI latent tuberculosis infection, QALYs quality-adjusted life years. The most influential input variables were risk of TB exposure (especially for intermediate-risk HCWs), risk of progression to active TB following new infection and risk of infection after exposure, risk of death with active TB, QALY decrements attributed to latent TB treatment and active TB, and proportion of workers performing high-risk duties
