Total number of audited variables and percentage of erroneous data by data type during initial audits at seven sites^a.

This table shows the number of variables audited in each of eleven categories of data, including gender, birth date, weight, CD4 count, viral load, antiretroviral (ARV) regimens, and all associated dates.

Columns contain the counts for each site (N), along with the percentage of data that was labeled “in error” by auditors (%err). The reported percentage of erroneous data includes incorrect, missing, and sourceless values (error categories 3, 4, and 5), but not minor errors.
