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
backgroundMesenchymal stromal/stem cells (MSCs) have potent immunomodulatory abilities, particularly in a milieu of hyperactive immune system, through secreting a number of cytokines, growth factors, bioactive compounds and peptides, and by cell-cell contact. During viral infection, failure of immuno-neutralization of the viral particles, recruits T-lymphocytes (T-cells) that clear the virally-infected cells. MSCs greatly potentiate T-cells anti-viral activity.
objectiveThe objective of this study is to assess the ability of the cytokine-primed MSCs to activated T-cells, towards an antiviral application.
methodHuman umbilical cord MSCs (UC-MSCs) were isolated from Wharton Jelly of a consented donor. UC-MSCs were primed with interferon (INF)-γ and transforming growth factor (TGF)-β1. Peripheral blood T-cells were isolated using mini-max and CD3+ population was purified using anti-CD3 immuno-magnetic beads. Naïve or primed MSCs were co-cultured with naïve and phytohemagglutinin (PHA)-activated CD3+ T-cells. T-cell activation was evaluated by changes in their rate of proliferation by cell count, flowcytometric immuno-phenotyping for CD25 expression, and IL-6 secretion in the conditioned medium.
resultsThe findings revealed that CD3+ T-cells count nonsignificant differed comparing the five experimental groups; Naïve MSCs, Naïve T cells, coculture with naïve MSCs, coculture with primed MSCs, and upon phytohemagglutinin-activation, despite a nonsignificant reduction of proliferation in the last two groups' coculture. Only the coculture with the primed MSCs showed significant activation of T-cells assessed as CD25 expression compared to the other groups (
conclusionThe cytokine-primed UC-MSCs significantly upregulated CD25+ expression on T-cells, while hindering IL-6, without affecting their proliferation rate. This may point to potentially stronger antiviral effects, while alleviating the viral infection-induced cytokine storm.
