Would there be an interest in filling out a questionnaire so I can create a linear regression model to determine if there is any correlation to define what symptoms best describe BFS and what remedies work best? I have attached a link to a website that has a link to download the questionnaire that is in Excel2007 format (click on “BFS Questionnaire”). If the file wants to download as a .zip extension, merely write over the .zip extension and save it as a .xlsx file. The answers to all questions must be numeric. The data (answers) in row 4 are my results that can be used as a guide. Please fill out row 5. You can send your results to me at . Any cell that has a red triangle has built in instructions which explain how to answer the questions – just place the computer cursor over the cell to read the comments / instructions. Please let me know if there are other questions that need to be added, but remember I may have to follow up with a second questionnaire. For instance, if the data/model suggests there is correlation between anti-convulsant medications and symptom relief then I will follow up with a questionnaire to gain more detail about what anti-convulsants people are using and the dosage. I want to try to keep this as anonymous as possible, so I am not asking people to place their names on the file, but a code (the last 5 digits of your phone number). The reason I need the code is to line up data between respondents if there is a follow up questionnaire. Remember, there is no guarantee there is any correlation between individual data (if this is the case we learn nothing), but we will not know until we try. In essence, each respondent will represent one equation in the model, so the more people that contribute, the better. If we move forward on this, I will post results on the same website. I am a retired engineer who suffers from BFS, I am not a doctor - only a person who wants to try to find some answers to our questions .
