Tornado histogram of lung cancer deaths in the low-dose CT screening scenario over the no screening scenario. EV effect value, horizontal line represents the relative difference in lung cancer deaths with low-dose CT screening over no screening (the higher the EV, the higher the screening benefits), and vertical dash line indicates the location of estimated average EV, prev lung cancer prevalence in the screened cohort, CTse sensitivity of low-dose CT, CTerl proportion of early-stage cancers among lung cancers detected with low-dose CT, srv_Er survival possibility of patients with resected early-stage lung cancers, NSerl proportion of early-stage cancers among lung cancers detected with no screening, CTidl proportion of indolent cancers among lung cancers detected with low-dose CT, fpMt death possibility due to false diagnosis and invasive treatment, srv_Ne survival possibility of individuals with resected non-early-stage lung cancer, trt_Er acceptance rate of surgery for early-stage lung cancers, CTsp specificity of low-dose CT, trt_Ne acceptance rate of surgery for non-early-stage lung cancers. Asterisk the proportion of difference squared between low and high EV for each variable of the sum of differences squared for all variables. The plus sign denotes that the higher the variable value, the greater the reduction in lung cancer deaths with low-dose CT screening over no screening, and the minus sign denotes that the higher the variable value, the smaller the reduction in lung cancer deaths with low-dose CT screening over no screening
