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

Microbial exopolysaccharides (EPSs) exhibit distinct physiological properties, including anti-inflammatory, anti-tumor, and anti-microbial activities that may have a range of industrial, pharmaceutical, and medical uses. This study aimed to separate, purify, and examine the properties of the Rhizobium sp. HR1101-4 EPS. The optimum parameter set (time, temperature, pH, sugar) for the production of EPS was determined. The highest yield was obtained at a temperature of 39 °C, a pH range of 8-10, and using mannose (0.2%) as the carbon source. The results of FT-IR and the NMR analysis revealed that the EPS is a mixture of hexoses with possible pentose sugars. Moreover, this structure showed positive antibiofilm activity against five pathogenic bacteria; Acinetobacter sp., Staphylococcus aureus, Shigella sonnei, Salmonella sp., and Shigella flexneri, as well as antioxidant activity (42%). Furthermore, the high water-holding (355%) and oil-holding capacity (170%) of the EPS may enhance the nutritional value and rheological characteristics of food products. The improved emulsifying activity of mustard oil suggested potential use for stabilizing emulsions. Additionally, the EPS showed promising flocculating activity, indicating its potential application in treatment of industrial wastewater. This also could be employed as a safe rheological agent and a nutritious food-grade additive for industrial use, paving the way for manufacturing innovation in near future.
