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

Lower back pain is a common problem in middle-aged and elderly people, and intervertebral disc degeneration (IVDD) is often the main cause. The present study aimed to explore the effects of dimethyl fumarate (DMF) on inflammation and oxidative stress in the intervertebral disc. C57/BL6 mice were used to construct an IVDD model by tail suspension and daily intraperitoneal injections of 10 mg/kg DMF were administered to analyze the effects of DMF on IVDD. In addition, human nucleus pulposus (NP) cells were cultured and stimulated cells with recombinant human IL-1β and DMF to examine the effects of DMF on inflammation and oxidative stress in NP cells. DMF significantly increased the intervertebral disc height index of mice and inhibited the degradation of the extracellular matrix of mouse NP tissue. In addition, DMF also decreased the expression of inflammatory factors [including IL-6, IL-8, matrix metalloproteinase (MMP)3 and MMP13] in NP cells. In terms of oxidative stress, DMF significantly increased the antioxidative stress response in NP cells and reduced endoplasmic reticulum stress. DMF also increased the activity of the nuclear factor erythroid 2-related factor (Nrf) 2/heme oxygenase (HO)-1 signaling pathway in NP cells and increased the phosphorylation of Akt. DMF also increased the anti-inflammatory and antioxidative ability of NP cells by promoting the activity of the Nrf2/HO-1 and PI3K/Akt signaling pathways, thus delaying IVDD.
