Six Trajectory groups of Medicaid users during 2 years prior to baseline in a New York City supportive housing program. This figure illustrates how individuals are grouped according to similarities in trajectories of monthly Medicaid expenditures over 2 years prior to baseline. No coverage (dark brown color); 0 cost (brown color); <20th % (light brown color); 20th % ~40th % (white color); 40th % ~60th % (light blue color); 60th % ~80th % (blue color); >80th % (dark blue color). Each horizontal line in the y axis represents an individual-level sequence of monthly Medicaid cost categories during 2 years prior to baseline. The x axis represents each month during two years prior to baseline. These individual-level sequences were stacked together and divided into 6 distinct clusters (or plots) based on their similarities. The height of the original plot was proportional to the number of individuals in each cluster, but then adjusted to the same size to more clearly show color patterns.
