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

backgroundTerminal restriction fragment length polymorphism (T-RFLP) analysis is a powerful tool to assess the diversity of a microbial community. In this study, we performed T-RFLP analysis of the fecal microbiota from patients with ulcerative colitis (UC) and those with Crohn's disease (CD).

methodsThirty-one patients with UC, 31 patients with CD, and 30 healthy individuals were enrolled. The polymerase chain reaction (PCR) products obtained from the 16S rRNA genes of fecal samples were digested with BslI, and T-RF lengths were determined.

resultsThe fecal microbial communities were classified into 5 clusters. Twenty-eight of the 30 healthy individuals and 17 of the 18 patients with inactive UC were classified into clusters I, II, and III, but these clusters included a small number of patients with active UC and inactive/active CD. In contrast, 8 of the 13 patients with active UC and the majority of CD patients (12 of the 16 patients with inactive CD, and 11 of the 15 patients with active CD) were included in clusters IV and V. Based on the BslI-digested T-RFLP database, the bacteria showed a significant decrease in the Clostridium family in patients with active UC and inactive/active CD. In contrast, Bacteroides were significantly increased in CD patients. No significant differences were observed between patients with active UC and those with active CD.

conclusionThe fecal microbial communities of IBD patients were different from those of healthy individuals. The gut microbiota of patients with inactive UC tended to be closer to that of healthy individuals, suggesting different roles for the fecal microbiota in the pathophysiology of UC and CD.
