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

Bacteria play an important role in the formation of primary Common Bile Duct (CBD) stones. However, the composition and function of the microbiota of bile duct in patients with primary CBD stones remained to be explored. We utilized the 16S rRNA gene high-throughput sequencing technology to analyze the microbial diversity and community composition of biliary and duodenal microbiota in 15 patients with primary CBD stones and 4 patients without biliary tract diseases. Alpha diversity analysis showed that the microbiota richness was similar in bile and intestinal fluid; Beta diversity analysis showed that there were differences in the composition between biliary microbiota and the duodenal microbiota, but the abundance of the main groups showed similarities. The composition of the biliary microbiota from gallstone patients was more complex, as was the duodenal microbiota.
