Text: the authors confirm that all data underlying the findings are fully available without restriction. here we confirm that there are ethical or legal restrictions on our data set that prohibit us from making the raw data publicly available. the study was approved by the institutional review board back in 2009, and was conducted from 20102011. at that time, secondary usage of acquired data by putting the data in a public repository was not included in the study plan, so we have not obtained the permission of the secondary usage from the irb or our subjects. however, we think that checking the validity of our study is not the secondary use of the data, and we are happy to provide the data upon request to anyone who contacts me (seiki konishi: skonishi@juntendo.ac.jp).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
