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

The aim of this study was to evaluate probiotic properties of ten Streptococcus thermophilus strains (st1 to st10) isolated from pickles in China. These strains all had β-galactosidase activity, which laid foundation for studying their probiotic properties. In this study, the bile salt hydrolase activity, lysozyme resistance, tolerance to simulated gastric juice, bile salt tolerance, and bacterial adhesion capacity to the Caco-2 cells of these selected strains were detected in vitro conditions. The results indicated that the bile salt hydrolase activities of st2, st6, and st9 were higher than that for other strains. St10 showed the greatest lysozyme resistance (> 80% survival), followed by st9, st8, st7, st5, and st6. As for the tolerance to simulated gastric juice, st5 possessed the highest survival rate (35%), followed by st6 (30%). St6 was the best performer in both bile salt tolerance and bacterial adhesion capacity to the Caco-2 cells. The results of fluorescence microscope and electron microscope further confirmed previous studies and more intuitively demonstrated the st6 strain's tolerance to harsh environments. Overall, these strains were expected to possess beneficial properties and have the potentiality to be probiotics.
