Flow charts showing the ability of participants to read and interpret (correctly or incorrectly) the 2704 standardized results of the Exacto Test HIV (Biosynex) obtained from successive random selection of a panel of 13 standardized tests, including 6 positive, 5 negative, and 2 invalid, including 988 by 76 female sew workers (FSWs) [A], and 1716 by 132 non-FSWs [C], and percentages of misinterpreted self-tests results by FSWs [B], and non-FSWs [D]. The heights of the vertical bars indicate the overall percentages of misinterpreted HIV self-test's results; the color-coded components of the bars indicated the type of misinterpretation: HIV-positive (black); HIV negative (white); invalid (gray).
