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

objectiveLactic acid bacteria (LAB) can improve disturbances of indigenous microflora as well as inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn's disease. We examined the anticolitic effect of Lactobacillus suntoryeus HY7801, which inhibited toll-like receptor (TLR)-4-linked NF-kappaB activation in human embryonic kidney (HEK) cells, in 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitic mice. MATERIALS AND

methodsWe measured the ability of commercial and intestinal LAB to inhibit lipopolysaccharide (LPS)-stimulated, TLR-4-linked NF-kappaB activation in HEK cells, as well as to inhibit colitis outcomes in TNBS-induced colitic mice. We also measured levels of the inflammatory markers, interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha, and IL-6, and their transcription factor, NF-kappaB, in intestinal mucosa by enzyme-linked immunosorbent assay and immunoblotting. RESULTS AND DISCUSSION: LAB inhibited TLR-4-linked NF-kappaB activation, and L. suntoryeus HY7801 was the most potent inhibitor. Intrarectal treatment of TNBS in mice caused colon shortening and also increased colonic expression of IL-1beta, IL-6, and TNF-alpha expression. However, oral administration of Lactobacillus HY7801 (100 mg/kg) inhibited colon shortening (p < 0.001) and myeloperoxidase activity in TNBS-induced colitic mice (p < 0.0002) and also decreased colonic expression of IL - 1beta (p < 0.003), IL-6 (p < 0.0001), and TNF-alpha (p < 0.0001). Lactobacillus HY7801 inhibited the NF-kappaB activation and TLR-4 expression induced by TNBS, as well as the expression of cyclooxygenase 2. Lactobacillus HY7801 also reduced the activity of intestinal bacterial glycosaminoglycan degradation and beta-glucuronidase induced by TNBS.

conclusionL. suntoryeus HY7801 can improve colitis via the inhibition of TLR-4-linked NF-kappaB activation.
