Cumulative risk of self-reported myocardial infarction/fatal coronary heart disease according to maximum total hydrocarbon (THC) exposure (parts per million (ppm)) during cleanup work (n = 23,923), Gulf Long-Term Follow-up Study, United States, 2010–2016. Risk estimates accounted for confounders (age, sex, education, smoking, and residential proximity to the spill) and predictors of censoring (age, education, ethnicity, smoking, cleanup work duration, and residential proximity to the spill) using inverse probability weights.
