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

In this study, the traditional fermentation starter (Daqu), a fermentation by-product (Huangshui) and fermentation grains (Zaopei) were combined with pit mud to provide the initial bacterial source, using a single pit mud bacterial inoculation source as the control group. Changes in metabolite accumulation and microbial community were assessed over six rounds of enrichment. Results showed that the addition of exogenous microorganisms (Daqu, Huangshui and Zaopei) better enhanced the quality of the enriched pit mud liquid compared to the use of multiple rounds of enrichment. The quality enhancement of the enriched pit mud liquid could be ranked in descending order as follows: Zaopei > Huangshui > Daqu. The quality of the enriched pit mud liquid was found to be highest in rounds 2-3 of the addition of Zaopei. These results provide theoretical guidance and technical support for the development of pit mud maintenance systems and techniques for the rapid aging of artificial pit mud.
