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

Out of the broad selection of analytical methods applied in metabolomic studies, liquid chromatography coupled to mass spectrometry (LC-MS) has the highest coverage potential. In that regard, the quality of the separation process is crucial for the analytical outcome. Reversed-phase (RP) and hydrophilic interaction liquid chromatography (HILIC) are widely applied, and the potential of various setups to combine these modes for more complementary data has been deeply explored. In our previous study on the orthogonality of LC conditions in the field of metabolomics, combinations of a mixed-mode phase with parallel RP and ion-exchange (IEX) properties and several HILIC columns exhibited the widest compound distributions in a two-dimensional (2D) separation space. For further performance evaluation, an offline comprehensive 2D-LC-TOF-MS (LC×LC-TOF-MS) system was set up with the mixed RP/IEX mode in the first dimension (
