GEOGRAPHIC DISTRIBUTION AND ENVIRONMENTAL TRIGGERS OF SYSTEMIC SCLEROSIS CASES FROM TWO LARGE ACADEMIC TERTIARY CENTERS IN MASSACHUSETTS: SUPPLEMENTAL FIGURES

Supplemental figures for Geographic distribution and environmental triggers of systemic sclerosis cases from two large academic tertiary centers in Massachusetts Supplemental Figure 1: Particulate matter and ash pollution show correlation with SSc period prevalence. Supplemental Figure 2: Geographic distribution of systemic sclerosis cases in conjunction with social justice index. An environmental justice (EJ) population follows any one of the following parameters: (1) “block group whose annual median household income is equal to or less than 65% of the statewide median ($62,072 in 2010),” or (2) “25% or more of the residents identify as a race other than white,” or (3) “25% or more of households have no one over the age of 14 who speaks English only or very well,” the latter being defined as “English Isolation.” Supplemental Figure 3: Zoomed in to better visualize Figure 2: The statistically significant association between SSc period prevalence in Massachusetts and chemical release sites, hazardous waste facilities, and oil or disposal sites together.
