Our study addressed a concern raised by a previous investigation that there was a high risk of childhood leukemia in Pennsylvania counties that have large amounts of hydraulic fracturing. We believe that replication of findings is a fundamental goal of science, and we sought to do so. Using the same data sets as the previous investigators, we found no association. We do not believe that following accepted scientific methods in an effort to replicate a previous finding fits the definition of obfuscation. Rather, it comports with good science.
