Sensitivity Analyses of a Scoring System for a Contraception Decision Aid.

We conducted formal analyses of a scoring system for a contraception decision aid to support transgender and gender-nonconforming (TGNC) assigned female at birth (AFAB) individuals. For this purpose, we developed a methodology framework to assess the weights for each decision factor, to conduct univariate and multivariate sensitivity analyses, and to provide data visualization, which led to successful identification of critical values in weight assignment that can impact the recommendations generated by the system. These analyses made critical contributions to development and validation of the system's knowledge base, providing explainable recommendations, and conducting additional research related to system users and functions. Future research is required to explore high-dimensional sensitivity analyses, to address technical issues identified, and to examine the generalizability of the methodology to other applications.
