“…The remaining 26 studies performed both univariate sensitivity analysis and probabilistic sensitivity analysis. Although it is recommended that the ranges used for sensitivity analysis be stated clearly and justified, many models did not specify the value ranges and their reasons [36,39,40,49,54,55,57,58,60,61,63,71,72]. Besides, only 12 studies clearly described and justified the choice of distribution for each parameter [25,30,33,35,37,38,42,47,50,53,57,67].…”
