The Longitudinal Study of Ocular Complications of AIDS was a 15-year multi-center observational study which collected demographic, medical history, treatment, and vision-related data at quarterly visits from 2,392 patients with AIDS. Each SAS dataset in this collection relates to the cumulative patient-visits from a particular LSOCA form. For example, va.sas7bdat is the SAS dataset for the visual acuity data. Use the appropriate LSOCA form and SAS labels from the SAS PROC CONTENTS to decode each data item.

This is the limited access database for the Study to Understand Fall Reduction and Vitamin D in You (STURDY) randomized response-adaptive clinical trial. The database includes baseline, treatment and post randomization data. This Database includes a set of files pertaining to the full study population (688 randomized participants plus screenees who were not randomized) and a set of files pertaining to the burn-in cohort (the 406 participants randomized prior to the first adjustment of the randomization probabilities). The Database also includes files that support the analyses included in the primary outcome paper published by the Annals of Internal Medicine (2021;174:(2):145-156). Each data file in the Database corresponds to a specific data collection form or type of data. This documentation notebook includes a SAS PROC CONTENTS listing for each SAS file and a copy of the relevant form if applicable. Each variable on each SAS data file has an associated SAS label. Several STURDY documents, including the final versions of the screening and trial consent statements, the Protocol, and the Manual of Procedures, are included with this documentation notebook to assist with understanding and navigation of STURDY data. Notes on analysis questions and issues are also included, as is a list of STURDY publications.
