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

Myeloid-derived suppressor cells (MDSCs) have emerged as a heterogeneic immunoregulatory population that can expand in response to inflammatory signals. Predominantly studied in cancer, MDSCs suppress T cells utilizing various mechanisms. In allogeneic hematopoietic stem cell transplantation (allo-HSCT) therapy-related toxicity and alloreactivity increase inflammatory cytokines that might favor an MDSC accumulation. To address this question, circulating CD14(+)HLA-DR(low/neg) cells were studied retrospectively in 51 allo-HSCT patients. These cells represent one of the few well-described human MDSC subsets under physiological and pathological conditions. The frequency of CD14(+)HLA-DR(low/neg) cells was significantly increased after allo-HSCT, especially in patients with acute graft-versus-host disease. Compared to healthy donor cells they were pSTAT1(low) (phosphorylated signal transducer and activator of transcription) and indoleamine 2,3-dioxygenase (IDO)(high). Serum levels of granulocyte colony-stimulating factor and interleukin-6, which both have been linked to MDSC induction, correlated positively with the frequency of CD14(+)HLA-DR(low/neg) cells. In vitro dysfunction of patient T cells, such as reduced proliferative capacity or CD3ζ-chain expression, was rescued by blocking the IDO activity of CD14(+)HLA-DR(low/neg) cells. Overall, we identified a T-cell-suppressive monocytic population that expands after allo-HSCT. The mechanisms responsible for such accumulation remain to be elucidated. It will be of great interest to prospectively investigate the influence of these cells on the graft-versus-tumor and -host reaction.
