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
This study developed a novel method of screening cryoprotectants used to improve the survivability of lyophilized Lactobacillus helveticus. To develop a liposome encapsulated β-galactosidase (β-gal) as a cell membrane model, the β-gal liposome was characterized in terms of mean size, poly dispersity index, zeta potential, along with transmission electron microscopy. 800 W of ultrasonic power and 10 min of sonication time were the optimal experimental conditions to obtain the desirable β-gal liposome. Subsequently, different cryoprotectants were mixed with the β-gal liposome during freeze-drying. After freeze-drying, liposomes were hydrolized, and the protective effect of cryoprotectants was assessed as the release rate of encapsulated β-gal. The lowest release rate of β-gal was obtained using 10 mg/100 ml trehalose and 0.2 mg/100 ml hyaluronic acid.
