Group 0 name Corresponds to the control (unexposed) group for case-control studies
HIV-negative children
Group 1 name Corresponds to the case (exposed) group for case-control studies
HIV-positive children on ART
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Children diagnosed with HIV and undergoing treatment with either non-nucleoside reverse transcriptase inhibitors (NNRTI) or protease inhibitor (PI/r)-based ART.
Group 0 sample size Number of subjects in the control (unexposed) group
82
Group 1 sample size Number of subjects in the case (exposed) group
87
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
Children were excluded from the study if they had taken antibiotics other than prophylactic co-trimoxazole within four weeks prior to sample collection.
