The probabilistic sensitivity analysis analyzes 1000 simulations of the model in which input parameters are randomly varied across pre-specified statistical distributions. The x-axis represents the WTP threshold. The acceptability curve showed that HTLV-1 antenatal screening is 81.1% cost-effective at a WTP threshold of US$50,000 per QALY gained. CE, cost-effectiveness; QALY, quality-adjusted life-year; WTP, willingness-to-pay; HTLV-1, human T cell leukemia virus 1.
