Lack of evidence for small intestinal mucosal T-cell activation as a pathogenic mechanism in African HIV-associated enteropathy.

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
The role of mucosal T-cell activation in HIV-associated enteropathy is uncertain. Twenty Zambian patients with AIDS and chronic diarrhea were studied, as were nine controls. Distal duodenal biopsies were taken at endoscopy. Morphometric analysis and dual color immunofluorescence staining were performed. Villous height was reduced [177 (118-228) vs 305 (244-358) microm P = 0.002] and crypt depth increased [220 (164-202) vs 194 (164-202) microm P = 0.008] in AIDS patients compared to controls. CD3+CD4+ T cells were reduced in AIDS patients compared to controls [12.9 (5.7-25.2) vs 47.6 (33.4-65.5)% P = 0.04]. There was no significant difference in expression of CD8, CD25, CD69, HML-1, or HLA-DR on T cells between the AIDS patients and controls, with the exception of CD3+HML-1+ cells, which were increased in AIDS patients (P = 0.05). Small intestinal T-cell activation was similar between AIDS patients and controls. We conclude, therefore, that this mechanism is not likely to be important in the pathogenesis of HIV-associated enteropathy.
