Notes

Variable labels, value labels, and source format strings are shown when they were preserved during import.
For categorical or labeled variables, n and % report the observed frequency distribution across displayed categories.
For continuous variables, n and % report non-missing observations; the Values of variable column is left blank.
Formatted examples display up to three observed values after applying available value labels and date formatting.
Long category lists are truncated after 20 displayed categories in this HTML export.
Percentages may not sum to exactly 100.0 because of rounding.
Some formatted categorical variables do not have attached value-label definitions in the imported file (strata2, n_partners, cd4_present, sxprnslt). Upload a labeled source file or keep a companion SAS catalog or formats text file available to recover code meanings.
