Competing Interests

Dr. Noel Bairey Merz would like to declare that she worked with QMED, Inc., Laurence Harbour, NJ, a commercial funder, in the context of receiving digital Holter monitors free of charge for several of other Women’s Ischemic Syndrome Evaluation (WISE) studies. This has no conflict of interest with the content of this paper as no Holters were used in the methods. Further, this does not alter the authors’ adherence to all the PLOS One policies on sharing data and materials. There are no other conflicts of interest to disclose among any of the investigators.
