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.

马萨诸塞州两所大型学术三级中心系统性硬化症病例的地理分布和环境触发因素补充图。
补充图1：颗粒物和灰尘污染与系统性硬化症时期患病率的关联性。
补充图2：系统性硬化症病例的地理分布与社会正义指数的结合。环境正义（EJ）人口符合以下任一参数：（1）“年度家庭收入中位数等于或低于全州中位数65%（2010年为62,072美元）的街区组”，或（2）“25%或更多的居民属于除白人以外的种族”，或（3）“25%或更多的家庭中没有人（14岁以上）仅使用英语或英语说得非常好”，后者定义为“英语孤立”。
补充图3：对图2进行放大以更好地可视化：马萨诸塞州系统性硬化症时期患病率与化学排放点、危险废物设施、石油或处置场所之间的统计学显著关联。
