Parameter sensitivity analysis for the PM using 100% of DS2-3. (a) represents that parameter a changes under fixed other model parameters. (b) represents that parameter b changes under fixed other model parameters. (c) represents that parameter c changes under fixed other model parameters. (d) represents that parameter d changes under fixed other model parameters. (e) represents that parameter e changes under fixed other model parameters.
