T cell receptor-Vβ repertoires in lung and blood CD4+ and CD8+ T cells of pulmonary sarcoidosis patients.
Article in BMC pulmonary medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundSarcoidosis patients have accumulations of activated CD4+ T cells in affected organs, such as the lungs. T cell receptor (TCR) Vβ-chain usage has been incompletely characterized in these patients.
methodsWe surveyed the TCR Vβ usage in CD4+ and CD8+ T cells in bronchoalveolar lavage (BAL) cells and peripheral blood mononuclear cells (PBMC) from 15 HLA-typed Scandinavian sarcoidosis patients. In addition, PBMC from 9 healthy volunteers and BAL cells from three of them were examined. Using 21 Vβ family-specific antibodies, we covered approximately 70% of all Vβ chains.
resultsIn BAL T cells from sarcoidosis patients, we identified 16 CD4+ T cell expansions in 271 analyses (5.9%) and 21 CD8+ expansions in 240 analyses (8.7%). In PBMC we found 9 CD4+ expansions in 276 analyses (3.3%) and 12 CD8+ expansions out of 263 analyses (4.6%). Consistent with previous studies we found Vβ8 and Vβ16 expansions in sarcoidosis patients' lungs. In addition, we found lung restricted Vβ22 expansions in three HLA DRB1 03+ patients. However, we found no statistically significant difference in frequency of expansions between patients and healthy controls.
conclusionsThe identified T cell expansions in present study indicate specific antigen recognition in the lungs of sarcoidosis patients.
