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

The aim of this study was to describe the microbial communities in the distal gut of wild wolves (Canis lupus). Fecal samples were collected from three healthy unrelated adult wolves captured at the nearby of Dalai Lake Nature Reserve in Inner Mongolia of China. The diversity of fecal bacteria was investigated by constructing PCR-amplified 16S rRNA gene clone libraries using the universal bacterial primers 27 F and 1493 R. A total of 307 non-chimeric near-full-length 16S rRNA gene sequences were analyzed and 65 non-redundant bacteria phylotypes (operational taxonomical units, OTUs) were identified. Seventeen OTUs (26%) showed less than 98% sequence similarity to 16S rRNA gene sequences were reported previously. Five different bacterial phyla were identified, with the majority of OTUs being classified within the phylum Firmicutes (60%), followed by Bacteroidetes (16.9%), Proteobacteria (9.2%), Fusobacteria (9.2%) and Actinobacteria (4.6%). The majority of clones fell within the order Clostridiales (53.8% of OTUs). It was predominantly affiliated with five families: Lachnospiraceae was the most diverse bacterial family in this order, followed by Ruminococcaceae, Clostridiaceae, Peptococcaceae and Peptostreptococcaceae.
