One-way sensitivity analysis results on number of averted HIV infections over five years for the PrEP intervention that considers 30% maximum uptake over 36 months for the following model parameters: adherence to oral PrEP, mean age of cohort, discontinuation from the PrEP intervention, and HIV testing frequency within the PrEP program. The x-axis represents number of infections averted over a five year time horizon and the y-axis is a categorical axis with the aforementioned model parameters as elements. The values written in parenthesis for each parameter represents the mean value (used in the base case) and range in which parameter values are varied, corresponding to lowest to highest number of infections averted, for each city.
