The company was not involved in sample collection and data interpretation, decision to publish, or preparation of the manuscript. Jay Magidson is an employee of Statistical Innovations. The company was not involved in sample collection and data interpretation, decision to publish, or preparation of the manuscript. Statistical Innovations only helped to carry out a stepwise logit analysis of the high-throughput qRT-PCR data to generate signature models. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
