Clinical and Microbial Determinants of Upper Respiratory Colonization With Streptococcus pneumoniae and Native Microbiota in People With Human Immunodeficiency Virus Type 1 and Control Adults.
Article in The Journal of infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundThe substantial risk for respiratory and invasive infections with Streptococcus pneumoniae (Spn) among people with HIV-1 (PWH) begins with asymptomatic colonization. The frequency of Spn colonization among US adults with and without HIV-1 infection is not well characterized in the conjugate vaccine era.
methodsWe determined Spn colonization frequency by culture and specific lytA gene quantitative polymerase chain reaction (PCR) and microbiota profile by 16S ribosomal RNA gene sequencing in nasopharyngeal (NP) and oropharyngeal (OP) DNA from 138 PWH and 93 control adults and associated clinical characteristics.
resultsThe frequencies of Spn colonization among PWH and controls did not differ (11.6% vs 8.6%, respectively; P = .46) using combined results of culture and PCR, independent of vaccination or behavioral risks. PWH showed altered microbiota composition (ie, β-diversity; NP: P = .0028, OP: P = .0098), decreased α-diversity (NP: P = .024, OP: P = .0045), and differences in the relative abundance of multiple bacterial taxa. Spn colonization was associated with altered β-diversity in the nasopharynx (P = .011) but not oropharynx (P = .21).
conclusionsDespite widespread conjugate vaccine and antiretroviral use, frequencies of Spn colonization among PWH and controls are currently consistent with those reported in the preconjugate era. The persistently increased risk of pneumococcal disease despite antiretroviral therapy may relate to behavioral and immunologic variables other than colonization.
