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

Reactive sulfur species (RSS) are a class of biological sulfur compounds that play significant roles in various physiological processes. Among these, trisulfides (RSSSR) have been recognized for their unique biological activities such as antioxidation. However, there is still a lack of suitable methods for the preparation of biothiol and protein trisulfides that will enable a better understanding of trisulfide's roles in RSS biology. In this study, we developed and analyzed the use of phthalimide-based disulfide reagents to generate trisulfides from thiols found abundantly in physiologically relevant environments. This approach was tested on both small molecule and larger protein thiols. The results demonstrated that this method provides access to both biothiol- and protein-based trisulfides and may facilitate further exploration of the functions of trisulfides in biological systems.
