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

Volatile sulfur compounds belong to the group of odor active compounds with very low sensory threshold levels and can influence the aroma of various products either in a positive or a negative way. Due to their high odor potency and their low sensory thresholds, it is critical to identify these substances in complex food matrices. A new instrumental setup based on the combination of a two-dimensional comprehensive gas chromatographic system with simultaneous dual detection based on a sulfur chemiluminescence detector and a time-of-flight mass spectrometer separation and identification was tested. Additionally, two different column configurations were tested and compared for further optimization of separation and selectivity. Three different roasted coffee samples were used to demonstrate the potential of this new instrumental configuration, keeping in mind the volatile and odor active fraction of roasted coffee being among one of the most complex volatile composition when comparing to other food and beverage products.
