In Vivo Target Engagement Assessment of Nintedanib in a Double-Hit Bleomycin Lung Fibrosis Rat Model.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Nintedanib is an anti-fibrotic medication endowed with a multi-kinase inhibitor profile and approved for the treatment of Idiopathic Pulmonary Fibrosis (IPF). Nintedanib is believed to inhibit mainly Vascular Endothelial Growth Factor (VEGF), Platelet-Derived Growth Factor (PDGF), and Fibroblast Growth Factor (FGF) receptor kinases. The main objective was to identify potential tissue and/or circulating biomarkers to demonstrate Nintedanib's target engagement and support its in vivo pharmacodynamic activity, consistent with its proposed mechanism(s) of action. In four independent experiments of bleomycin (BLM)-induced lung fibrosis model in rats, animals received Nintedanib (oral, 100 mg/kg/day) from day 7 post-BLM for 3 weeks. As expected, Nintedanib significantly reduced lung weight, the levels of lung fibrotic markers, and fibrotic areas. Moreover, Nintedanib-treated animals expressed lower levels of FGF2 in lung homogenates and higher plasma and lung levels of VEGF (≥3-fold,
