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

backgroundThe current study explored the characteristics of γδ T cells in the blood of HBV-associated acute-on-chronic liver failure (HBV-ACLF) patients and examined the relationship between γδ T cells and the clinical parameters.

methodsBlood samples were obtained from 26 patients with HBV-ACLF, 40 patients with chronic hepatitis B virus (HBV) infection (CHBV), and 25 healthy controls (HC). The frequencies of γδ T cells, subtype Vδ1T or Vδ2T, and CD45RO(+)γδ T cells were determined using flow cytometry. Intracellular cytokine staining analysis was used to evaluate the proportion of the IFN-γ-, TNF-α-, or IL-17-producing γδ T cells, and CD107a- or granzyme B-positive γδ T cells.

resultsWe found that the proportion of γδ T cells in blood samples from HBV-ACLF patients was much lower than in samples from CHBV patients or healthy controls. After stimulation with PMA and ionomycin, γδ T cells from HBV-ACLF patients produced the greatest amount of TNF-α or IL-17 among the three groups. Granzyme B- or CD107a-positive γδ T cells were significantly more frequent than in CHBV or control samples. There was a negative correlation between the percent of TNF-α(+)γδ T cells and ALT or AST levels, and between the percent of CD107a(+)γδ T cells and TBiL or DBiL levels.

conclusionsThese results suggest that γδ T cells might participate in liver injury in HBV-ACLF patients by producing increased amounts of inflammatory cytokines and/or cytotoxicity ability. These findings provide novel information regarding the pathogenesis of HBV-ACLF.
