The surveys were performed by uniformly-trained qualified investigators in a face-to-face form before the start of the post-remission therapy to fill in the questionnaires truthfully and obtain patient-related information. All questionnaires had been reviewed by the survey leader. Investigators were familiar with the contents of the questionnaires for this study, but the purpose of this study was confidential to prevent interview bias.
