NA, not applicable; NR, not reported; VCT, voluntary counselling and testing.
a A score of 1 indicates that the article met the criterion; a score of 0 indicates that it did not. However, studies with mixed designs have been given 1 point in this table.
b If a probability sample was used to select participants, a “1” is in the column. Similarly, if a mixed sampling strategy was used but randomization was conducted in at least one sampling frame, a “1” is in the column. If a census sample of all individuals receiving the intervention was used for assessment, a “1” is also in the column. If a non-probability sample was used, a “0” is in the column.
