Neuroprotective effects of chemical constituents from Nicotiana tabacum L. in Parkinson's disease.
Article in Natural products and bioprospecting, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
Parkinson's disease (PD), the second most common neurodegenerative disorder globally, arises from selective dopaminergic neuron degeneration. While current therapies address symptoms, disease-modifying agents remain an unmet need. Herein, we investigated Nicotiana tabacum L. (Solanaceae), a plant linked epidemiologically to reduced PD risk, as a source of multi-target neuroprotective compounds. From ultra-low nicotine (< 0.04%) tobacco leaves, we isolated 22 molecules, including a novel 21-norsesterterpenoid (Nicotiazanorpenoid A) and eight previously unreported compounds. Systematic evaluation revealed three synergistic neuroprotective mechanisms: (1) Antioxidant activity: Scopoletin (3) and isoferulic acid (6) showed significant radical scavenging capacity (ABTS assay; IC
