Probabilistic sensitivity analyses (2000 Monte Carlo simulations). Each dot in the plot represents the results of 1 Monte Carlo simulation. X-axes represent incremental benefits (adverse events averted), and y-axes represent incremental costs in CHF. Dots on the southeast quadrant means the drug in bold typeface is dominant (ie, less costs and more benefits). Dots on the northwest means the drug in bold typeface is dominated (more costs and less benefits). Dots on either northeast and southwest quadrants mean that trade-offs between costs and benefits of the drugs being compared exist, and dots below the threshold (slope of line from the origin) are considered cost-effective.
