Take the following as truth: The HEI re-examination lends credibility to the original studies but also found unexpected sensitivities concerning (a) which pollutants are most important, (b) the role of education in mediating the association between pollution and mortality, and (c) the magnitude of the association depending on how spatial correlation was handled.
Then the following statement: "The HEI re-examination makes the original study seem credible because it was so well-researched." is true, false, or inconclusive?
Answer: Inconclusive
