Symptoms listed are those present at the time of the patient’s return to the clinic to collect the smear microscopy results. All patients enrolled in the study had prolonged cough and/or other symptoms of TB at the time of collection of the first sputum specimen.
TB = tuberculosis; HIV = human immunodeficiency virus; ART = antiretroviral treatment; + = positive; − = negative; NA = not applicable; ND = not done; Suggestive = radiological signs suggestive of active TB.
