The impact of blood Transfusion on T Helper Cells and Cytokines in Transfusion-Refractory Patients: a Prospective Study.

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
Red blood cell (RBC) transfusion can increase patients' hemoglobin levels and improve hypoxia. The factors affecting the transfusion efficacy include immune and nonimmune factors. The objective of this study was to explore the impact of blood transfusion on T helper (Th) cell ratios and levels of serum cytokines in RBC transfusion-refractory patients. In this prospective study, anemic patients receiving RBC transfusion were enrolled. Peripheral venous blood samples were extracted from patients before RBC transfusion and within 24 h after transfusion. Th cell ratios and levels of serum cytokines were detected by flow cytometry. Differences in Th cell ratios and levels of serum cytokines (IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ) between pretransfusion and posttransfusion were compared. A total of 47 patients agreed to participate in this study. They were grouped according to incremental Hb levels, 20 (42.55%) patients were divided into the RBC transfusion refractory group, while 27 (57.45%) patients were in the validity group. The expected Hb increment was defined by a panel of Chinese experts. In RBC transfusion-refractory patients, Th1 and Th2 cell ratios increased while levels of serum IL-2 and IL-10 decreased after transfusion. In RBC transfusion validity patients, there were no significant changes in Th cell ratios or levels of serum cytokines between pretransfusion and posttransfusion. We found that Th1 and Th2 cell ratios increased while serum IL-2 and IL-10 levels decreased after transfusion in RBC-refractory patients.
