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

This study aimed to evaluate the safety of Clostridium butyricum and to investigate the effect of C. butyricum on mice ecosystem in the intestinal tract by way of examining the population of different microorganisms isolated from caecal contents. We firstly evaluated the safety of C. butyricum using acute toxicity test and Ames test. Then forty male BALB/c mice were divided into the following four treatment groups, each consisting of ten mice: normal group, low-dose group, medium-dose group and high-dose group. Caecal contents were removed aseptically, immediately placed into an anaerobic chamber, and dissolved in sterile pre-reduced PBS. The determination of Enterococcus spp., Enterobacter spp., Lactobacillus spp., Bifidobacterium spp. and Clostridium perfringens was analyzed by the spread plate method, cell morphologies and biochemical profiles. The results showed the oral maximum tolerated dose of C. butyricum was more than 10 g/kg body weight in mice and no mutagenicity judged by negative experimental results of Ames test. And in medium- and high-dose groups, the populations of Bifidobacterium spp. and Lactobacillus spp. increased in caecum, as well as the ratios of Bifidobacterium spp. and Lactobacillus spp. to Clostridium perfringens (P < 0.01) as compared with the normal group. This research showed the intake of C. butyricum significantly improved the ecosystem of the intestinal tract in BALB/c mice by increasing the amount of probiotics and reducing the populations of unwanted bacteria.
