Brief Report: Cessation of Long-Term Cotrimoxazole Prophylaxis in HIV-Infected Children Does Not Alter the Carriage of Antimicrobial Resistance Genes.
Trial report in Journal of acquired immune deficiency syndromes (1999), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCotrimoxazole (CTX) is a broad-spectrum antimicrobial, combining trimethoprim and sulfamethoxazole. CTX prophylaxis reduces mortality and morbidity among people living with HIV in regions with high prevalence of bacterial infections and malaria. The Antiretroviral research for Watoto trial evaluated the effect of stopping versus continuing CTX prophylaxis in sub-Saharan Africa.
methodsIn this study, 72 HIV-infected Zimbabwean children, on antiretroviral therapy, provided fecal samples at 84 and 96 weeks after randomization to continue or stop CTX. DNA was extracted for whole metagenome shotgun sequencing, with sequencing reads mapped to the Comprehensive Antibiotic Resistance Database to identify CTX and other antimicrobial resistance genes.
resultsThere were minimal differences in the carriage of CTX resistance genes between groups. The dfrA1 gene, conferring trimethoprim resistance, was significantly higher in the continue group (P = 0.039) and the tetA(P) gene conferring resistance to tetracycline was significantly higher in the stop group (P = 0.013). CTX prophylaxis has a role in shaping the resistome; however, stopping prophylaxis does not decrease resistance gene abundance.
conclusionsNo differences were observed in resistance gene carriage between the stop and continue groups. The previously shown multi-faceted protective effects of CTX in antiretroviral research for Watoto trial clinical outcomes are not outweighed by the risk of multi-drug resistance gene selection due to prophylaxis. These findings are reassuring, given current recommendations for long-term CTX prophylaxis among children living with HIV in sub-Saharan Africa to decrease mortality and morbidity.
