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

Capitalizing on the massive increase in sample concentrations which are produced by extremely low elution volumes, nanoliquid chromatography-electrospray ionization-tandem mass spectrometry (nano-LC-ESI-MS/MS) is currently one of the most sensitive analytical technologies for the comprehensive characterization of complex protein samples. However, despite tremendous technological improvements made in the production and the packing of monodisperse spherical particles for nanoflow high-pressure liquid chromatography (HPLC), current state-of-the-art systems still suffer from limits in operation at the maximum potential of the technology. With the recent introduction of the μPAC system, which provides perfectly ordered micropillar array based chromatographic support materials, completely new chromatographic concepts for optimization toward the needs of ultrasensitive proteomics become available. Here we report on a series of benchmarking experiments comparing the performance of a commercially available 50 cm micropillar array column to a widely used nanoflow HPLC column for the proteomics analysis of 10 ng of tryptic HeLa cell digest. Comparative analysis of LC-MS/MS-data corroborated that micropillar array cartridges provide outstanding chromatographic performance, excellent retention time stability, and increased sensitivity in the analysis of low-input proteomics samples and thus repeatedly yielded almost twice as many unique peptide and unique protein group identifications when compared to conventional nanoflow HPLC columns.
