Low-dose Drosera rotundifolia induces gene expression changes in 16HBE human bronchial epithelial cells.
Article in Scientific reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Drosera rotundifolia has been traditionally used for the treatment of respiratory diseases in phytotherapy and homeopathy. The mechanisms of action recognized so far are linked to the known effects of specific components, such as flavonoids, but are not completely understood. In this study, the biological functions of D. rotundifolia were explored in vitro following the treatment of bronchial epithelial cells, which are the potential targets of the pharmacological effects of the herbal medicine. To do so, the whole plant ethanolic extract was 1000-fold diluted in water (D. rotundifolia 3×) and added to a 16HBE human cell line culture for 3 h or 6 h. The effects on gene expression of the treatments and corresponding controls were then investigated by RNA sequencing. The differentially expressed genes were validated through RT-qPCR, and the enriched biological functions involved in the effects of treatment were investigated. D. rotundifolia 3× did not impair cell viability and was shown to be a stimulant of cell functions by regulating the expression of dozens of genes after 3 h, and the effects were amplified after 6 h of treatment. The main differentially expressed genes encoded ligands of epithelial growth factor receptor, proteins involved in xenobiotic detoxification and cytokines, suggesting that D. rotundifolia 3× could stimulate self-repair systems, which are impaired in airway diseases. Furthermore, D. rotundifolia 3× acts on a complex and multifaceted set of genes and may potentially affect different layers of the bronchial mucosa.
