Functionalised thin multi-walled carbon nanotubes are less toxic to lung cells in vitro than their native counterparts.
Article in Archives of toxicology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Functionalisation of carbon nanotubes (CNTs), to make them more hydrophilic, is an essential step in their preparation for use in a wide range of industrial processes. The toxicological impact of these modifications has been investigated. However, due to the diversity of experimental models used in studies, no consensus has yet been reached. Here, we studied the toxicity of multi-walled CNT (MWCNT) with or without hydroxyl or carboxyl functional groups in lung cell models-chosen due to the risk of inhalation exposure for employees during handling of nanomaterials. In this study, we investigated the induction of the epithelial-mesenchymal transition (EMT) of human bronchial epithelial cells BEAS-2B following 6 weeks of treatment with MWCNTs ranging from 0.125 to 1 µg/cm
