Source documents are defined as original documents, data and records. These may include hospital records, clinical and office charts, lab results, cognitive data and information, etc. The Case Report Form documents will serve as the source records for this trial. All forms will be completed within 5 business days of the study visit. A CRF will be provided for each enrolled study subject. All CRFs will be completed using black ink. All corrections will be made by striking through with a single line and writing correct data above, beside, or below the erroneous data, so as not to obscure the original entry. Each correction will be initialed and dated by the person making the correction.
