Fig. 2From: Trade-off between benefits, harms and economic efficiency of low-dose CT lung cancer screening: a microsimulation analysis of nodule management strategies in a population-based settingSchematic representation of modelled NELSON-like nodule management protocol. V cut and VDT cut indicate the threshold values of the volume and volume doubling time which indicate a cancer positive result. V fup represents low threshold volume for a follow-up examinationBack to article page
