Differential regulation and function of tumor-infiltrating T cells in different stages of breast cancer patients.
Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Breast cancer survival was associated with higher frequencies of CD8(+) T cytotoxic T cells in infiltrating lymphocytes. On the other hand, the frequency of CD4(+)CD25(+)FoxP3(+) regulatory T cells was inversely correlated with clinical outcomes of breast cancer. The regulation and interaction of different types of tumor-infiltrating T cells in different stages of breast cancer patients are still unclear. In this study, we examined the functions and regulations of CD8(+) T cells and CD4(+)CD25(+)FoxP3(+) T cells from resected tumors from 12 stage I, 24 stage II, and 20 stage III untreated breast cancer patients. We found that tumor-infiltrating CD8(+) T cells from stage III patients were more refractory to T cell receptor (TCR) stimulation than those from stage I and stage II patients in terms of interferon gamma (IFN-γ) production and proliferation. On the other hand, tumor-infiltrating CD4(+)CD25(+)FoxP3(+) T cells had higher proliferation in stage III tumors than in stage I and stage II tumors. In addition, we found that tumor-infiltrating CD4(+)CD25(+) T cells can suppress CD8(+) T cell inflammation ex vivo. Altogether, our data demonstrated that stage III tumors in breast cancer patients had a more immunosuppressive microenvironment.
