Feasible and effective reuse of municipal sludge for vegetation restoration: physiochemical characteristics and microbial diversity.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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 large volume of municipal sludge causes environmental problems in cities worldwide. In this study, municipal sludge, mixed with construction waste residue, was used as substrate to plant Ailanthus altissima. The growth of A. altissima, the substrate characteristics, and substrate microbial diversity were measured to investigate potential recycling and reusing pathways of municipal sludge. The obtained results showed that compared to garden soil, the mixed substrate was weakly alkaline, and had higher nutrient contents, which is beneficial for A. altissima, and results in better growth in mixed substrate. Although the contents of the main heavy metals in the mixed substrate were significantly higher than in garden soil, the values met the criterion of Class II soil in the Environmental Quality Standard for the Soils of China (GB15618-1995). Different substrates showed a variety of microbial diversities. Proteobacteria was the top microbial phylum in all samples, and higher relative abundances were found in samples containing municipal sludge. After growing A. altissima, the relative abundances of Acidobacteria and Gemmatimonadetes increased in the mixed substrate. Therefore, addition of construction waste residue and growth of A. altissima caused a difference. The microbial communities in the mixed substrate with A. altissima are both plant friendly and environmentally friendly. These results suggest this mixed substrate as a potentially feasible and effective pathway for the reuse and recycling of municipal sludge for vegetation restoration.
