Randomization Sequence Generation
We used a random sequence generator programmed into the web-based tool to assign each participant upon login to the LCSDecTool vs control intervention. Randomization was blocked by study site. The random allocation sequence was generated by the website developers and study staff. The research associates who enrolled participants (J.M.P., J.M., J.V.I., D.A.D., and J.B.R.) were not aware of group assignment prior to the enrolled participant logging on to the web-based program.
