Residual host cell proteins: sources, properties, detection methods and data acquisition modes.
Review in Frontiers in microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Host cell proteins (HCPs) are process-related impurities derived from host organisms used for recombinant protein production in biopharmaceutical manufacturing. The generation of HCPs may lead to potential safety risks, such as immunogenicity, reduced drug efficacy and long-term side effects. Therefore, in the biopharmaceutical process, even trace amounts of HCPs need to be strictly regulated and controlled. The main bottlenecks associated with the detection of HCPs include a wide dynamic range of detection and instability of HCPs. Due to its high sensitivity and high resolution, mass spectrometry has attracted more and more attention in HCP detection, but it still cannot completely replace enzyme-linked immunosorbent assay (ELISA). The research in the future includes the development of more efficient sample pretreatment methods and data processing techniques to improve the sensitivity and accuracy of detection. At the same time, combined with risk assessment and process optimization, it is expected to further reduce the residual risk of HCP. This review discusses the sources, properties, pretreatment and detection of residual HCPs in therapeutic products, along with current regulatory considerations and future advancements.
