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

While oyster mushroom (Pleurotus spp.) is one of the most popular cultivated edible mushrooms, there is scanty information about the microbial community taking part in mushroom substrate production. In this study, an improved sequence-aided terminal restriction fragment length polymorphism (T-RFLP) was used to identify and (semi-)quantify the dominant bacteria of oyster mushroom substrate preparation. The main features of the improved T-RFLP data analysis were the alignment of chromatograms with variable clustering thresholds, the visualization of data matrix with principal component analysis ordination superimposed with cluster analysis, and the search for stage-specific peaks (bacterial taxa) with similarity percentage (analysis of similarity) analysis, followed by identification with clone libraries. By applying this method, the dominance of the following bacterial genera was revealed during oyster mushroom substrate preparation: Pseudomonas and Sphingomonas at startup, Bacillus, Geobacillus, Ureibacillus, Pseudoxanthomonas, and Thermobispora at the end of partial composting, and finally several genera of Actinobacteria, Thermus, Bacillus, Geobacillus, Thermobacillus, and Ureibacillus in the mature substrate. As the proportion of uncultured bacteria increased during the process, it is worth establishing strain collections from partial composting and from mature substrate for searching new species.
