“Fetal Deaths and Proximity to Hazardous Waste Sites in Washington State” & “Intensive Lipid Lowering With Atorvastatin in Patients With Coronary Artery Disease, Diabetes, and Chronic Kidney Disease,”
What population is researched in each article?.
What data are collected in each article? What are the independent events or variables? What are the dependent events or variables? Evaluate whether the authors make appropriate claims related to the independence or dependence of the events or variables they investigate
The population used in the article, Fetal Deaths and proximity to Hazardous Waste Sites in Washington State, were women with fetal deaths at 20 weeks using Washington State vital records from 1987 to 2001. This resulted in 7054 cases. Then the locations of 939 hazardous waste sites were determined using the Department of Ecology registry. Then the distance was determined from the maternal delivery point to the hazardous waste site. Then the odds ratio and 95% confidence interval were calculated.
The independent variables in this article are the vital records studied form Washington State health records, the choosing of 20 weeks as the stage of development of fetuses in which to research the fetal deaths, and the hazardous waste sites as determined by the Department of ecology registry, then determining the distances from each waste site to maternal delivery residence to measure. The dependent variable was the actual number of fetal deaths observed using the independent variables and the proximity to a registered hazardous waste site. Using these dependent and independent variables the appropriate claims of no observable increase in fetal deaths were observed due to close proximity to hazardous waste sites. The statement that the close proximity to pesticide waste sites may increase fetal death is not substantially documented in the results of the sample though making this a less appropriate claim.
