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

Interleukin (IL)-34 is a new pro-inflammatory cytokine with elevated expression in rheumatoid arthritis (RA) patients. Our previous study showed that the frequency of T helper 17 (Th17) cells was also elevated in RA patients. Our study aimed to determine the effects of IL-34 on the proliferation, transcription factor expression and cytokine secretion of different subgroups of CD4 + T cells [Th1, Th2, Th17 and regulatory T (Treg) cells] in RA patients. Peripheral blood mononuclear cells (PBMCs) were isolated from the peripheral blood of 10 RA patients and stimulated with different concentrations of recombinant human (rh) IL-34 (0, 25, 50 and 100 ng/ml). Flow cytometry was used to determine the frequencies of the 4 subgroups of CD4 + T cells. Reverse transcription-PCR, western blotting and enzyme-linked immunosorbent assays were used to determine the mRNA and protein expression levels of transcription factors and cytokines. As a result, the frequency of Th17 cells was obviously increased under IL-34 stimulation. Moreover, the expression of the transcription factor retinoic acid-related orphan receptor (ROR-γt) and secretion of IL-17 by PBMCs were increased by stimulation with IL-34. However, there were no effects of IL-34 on transcription factors or cytokine secretion in Th1, Th2 and Treg cells. In conclusion, IL-34 can improve the proliferation of Th17 cells and expression of IL-17 in RA patients.
