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

Organic-inorganic hybrid nanoflowers (hNFs) have high stability, reusability, low production cost, and overcome substrate/product inhibition. Antimicrobial activity of various hNFs has been reported to overcome environmental microbial contaminations and infections, which are considered major public health problems. α-amylase, protease, and lipase are the most common industrial enzymes exerting antimicrobial activity; therefore, we synthesized triple enzyme (α-amylase, protease, and lipase)-embedded hNFs by using pancreatin to evaluate their antimicrobial activity in comparison with one of the most potent antimicrobial polymer chitosan. The broad spectrum of the antimicrobial properties of chitosan is used in industrial products, including cosmetics, food, agriculture, pharmaceuticals, and textiles. SEM analysis, thermogravimetric analysis (TGA), and the degree of deacetylation (%DD) were performed for chitosan characterization, where SEM, FTIR, EDX, and XRD analyses were performed for the characterization of hNFs. The catalytic activity of pancreatin and hNFs was evaluated by measuring lipase, α-amylase, and protease enzyme activities at 37 °C. Antibacterial activities of hNFs, pancreatin, and chitosan were tested on gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria, compared to the pancreatin and chitosan via agar and broth dilution methods. hNFs showed enhanced catalytic activity for protease, lipase, and α-amylase compared to pancreatin at different pH values (pH 8, 9). hNFs showed catalytic activity after being washed and reused up to six times, indicating their reusability and recoverability. hNFs showed significant antimicrobial activity, such as chitosan, Staphylococcus aureus, and Escherichia coli, compared to pancreatin. Our novel hNFs can be used to develop antimicrobial technologies to fight against environmental microbial contaminations and antibiotic resistance-driven environmental pathogens.
