Prognostic Role of Adaptive Immune Microenvironment in Patients with High-Risk Myelodysplastic Syndromes Treated with 5-Azacytidine.

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
BACKGROUND/
objectivesThere are limited data regarding immunohistochemical profiling of immune cells in bone marrow trephine biopsies of patients with high-risk myelodysplastic syndromes (HR-MDS).
methodsWe sought to objectively quantify, with the use of digital pathology, the density (cells/mm2) of the prominent adaptive immunity cell populations in sixty-four (64) bone marrow trephine biopsies of HR-MDS patients receiving 5-Azacytidine. We focused on CD3(+) T cells, CD8(+) cytotoxic T cells (Tc), helper T cells (Th), Foxp3(+) regulatory T cells (Tregs), CD20(+) B-cells and CD138(+) plasma cells and evaluated the presence and the number of lymphoid aggregates. A control group of twenty "non-MDS" patients was included in the study.
resultsWe identified a significant decrease in adaptive immune cell densities in the HR-MDS patients compared to the non-MDS controls. Increased T and Th cell densities correlated with the response to 5-Azacytidine (5-AZA) treatment. Higher T, Tc, Th and plasma cells densities and low B, Tregs and Tregs/T cells ratios correlated with increased overall survival. Reduced Tregs, Tregs/T cells, Tregs/Tc and plasma cells showed improved leukemia-free survival. A modified IPSS-R (IPSS-R-I), combining the initial IPSS-R with the immune populations' parameters, improved overall survival and showed a double-fold increase in Cox calculated hazard ratios.
conclusionsImmunohistochemical bone marrow immune profiling represents a powerful and easily useable tool for investigating the possible role of bone marrow immune microenvironment in the pathogenesis and progression of MDS, but also its association with the response to 5-AZA treatment and clinical outcomes.
