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

A modular and adaptive mass spectrometry (MS)-based platform was developed to provide fast, robust and sensitive host cell protein (HCP) analytics to support process development. This platform relies on one-dimensional ultra-high performance liquid chromatography (1D UHPLC) combined with several different MS data acquisition strategies to meet the needs of purification process development. The workflow was designed to allow HCP composition and quantitation for up to 20 samples per day, a throughput considered essential for real time bioprocess development support. With data-dependent acquisition (DDA), the 1D UHPLC-MS/MS method had excellent speed and demonstrated robustness in detecting unknown HCPs at ≥ 50 ng/mg (ppm) level. Combining 1D UHPLC with sequential window acquisition of all theoretical spectra (SWATH) MS enabled simultaneous detection and quantitation of all HCPs in single-digit ng/mg range within 1 hour, demonstrating for the first time the benefit of SWATH MS as a technique for HCP analysis. As another alternative, a targeted MS approach can be used to track the clearance of specific known HCP under various process conditions. This study highlights the importance of designing a robust LC-MS/MS workflow that not only allows HCP discovery, but also affords greatly improved process knowledge and capability in HCP removal. As an orthogonal and complementary detection approach to traditional HCP analysis by enzyme-linked immunosorbent assay, the reported LC-MS/MS workflow supports the development of bioprocesses with optimal HCP clearance and the production of safe and high quality therapeutic biopharmaceuticals.
