Proposed Analysis: We would like to use a longitudinal dataset with the effect of a drug (E.g. Lecithin) on Alzheimers. The data should have the exact date recorded, treatment group (control, treatment), and response (such as cognitive score). Our goal is to use the continuous visit time to draw conclusions about the data, as most studies involve 'binning' the time variable into the categories generated by the protocol-e.g. 1-month, 3-month, 6-month, etc visits. I hope you have a dataset for this purpose and that I may use it for my research. Thanks
