1 · What the graph read from it

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.

2 · The registry

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

objectivesTo evaluate the impact of HIV infection on colonization resistance in the proximal gut.

designIt was a case-control study.

methodsWe contrasted microbiota composition between eight HIV-1-infected patients and eight HIV-negative controls to characterize community alteration and detect exogenous bacteria in the esophagus, stomach, and duodenum, as well as the mouth using a universal 16s ribosomal RNA gene survey and correlated the findings with HIV serostatus and peripheral blood T-cell counts.

resultsHIV infection was associated with an enrichment of Proteobacteria (P=0.020) and depletion of Firmicutes (P = 0.005) in the proximal gut. In particular, environmental species Burkholderia fungorum and Bradyrhizobium pachyrhizi colonized the duodenum of HIV patients who had abnormal blood CD4 T-cell counts but were absent in HIV-negative controls or HIV patients whose CD4 cell counts were normal. The two species coexisted and exhibited a decreasing trend proximally toward the stomach and esophagus and were virtually absent in the mouth. B. fungorum always outnumbered B. pachyrhizi in a ratio of approximately 15 to 1 regardless of the body sites (P < 0.0001, r = 0.965). Their abundance was inversely correlated with CD4 cell counts (P = 0.004) but not viral load. Overgrowth of potential opportunistic pathogens for example, Prevotella, Fusobacterium, and Ralstonia and depletion of beneficial bacteria, for example, Lactobacillus was also observed in HIV patients.

conclusionsThe colonization of the duodenum by environmental bacteria reflects loss of colonization resistance in HIV infection. Their correlation with CD4 cell counts suggests that compromised immunity could be responsible for the observed invasion by exogenous microbes.
