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 present study aims to carefully delineate the bacterial community composition in marine sediments from different geographical coastal regions of Palk Bay and Gulf of Mannar that are known for human recreational activities. Bacterial richness in different marine sediments was assessed using 16S rRNA gene-based Denaturing Gradient Gel Electrophoresis (DGGE) which is a widely deployed fingerprinting technique. The DGGE profiles revealed that the bacterial community profiles of sediment from different coastal regions were complex and dynamic. The most dominant phylum present in the marine sediment samples were Proteobacteria followed by Cyanobacteria, Bacteriodetes, Firmicutes, Acidobacteria, and Actinobacteria. Cosmopolitan presence of Thioalkalivibrio sp. was observed in all the marine sediments. Sequencing of the abundant band reveals the presence of Vibrio spp. in all the marine sediments. Comparative illumina data analysis revealed the presence of 51 different Vibrio species in which Vibrio alginolyticus holds the highest abundance (67.2%) followed by V. harveyi (13.5%). This is the one of the very few reports that compared the complex microbial community composition of the marine sediments of different geographical regions of unexplored coastal region. Further in-depth analysis needs to be taken to understand the presence of complex microbial compositions and their functions through high-throughput whole metagenome sequencing and metaproteomic approaches.
