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
Background: Lung cancer (LC) persists as a leading cause of global cancer-related mortality. Pathological angiogenesis constitutes a critical mechanism in LC progression, facilitating neovascularization that supplies oxygen and nutrients to support tumor growth. Despite this, current anti-angiogenic therapies face significant clinical limitations. Danggui Buxue Decoction (DBD), a traditional Chinese herbal formula used to tonify Qi and activate blood circulation, exhibits clinical potential in delaying LC progression; however, its precise mechanistic basis remains incompletely defined. This study aimed to evaluate the inhibitory effects of DBD aqueous extract on lung tumors in 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced A/J mice and elucidate whether its therapeutic mechanism involves suppression of hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor-A (VEGF)-mediated angiogenesis. Methods: Potential therapeutic targets of DBD against LC were identified through database mining (OMIM, TTD, GeneCards) using topological analysis. A/J mice received intraperitoneal injections of NNK (100 mg/kg) to induce lung tumors. From week 10, DBD aqueous extract (10 g/kg/day) was administered via oral gavage. Lung tumor progression and systemic parameters were assessed at weeks 10 and 20 using small-animal computed tomography (CT), enzyme-linked immunosorbent assay (ELISA), Doppler ultrasound, pulmonary function tests, and complete blood counts (CBCs). At week 20, mice were anesthetized with 3% isoflurane and sacrificed by cervical dislocation. Lung tissues were harvested for histopathological evaluation (H&E), immunohistochemistry (CD31), and immunofluorescence (HIF-1α/VEGF) to quantify microvessel density and hypoxia/angiogenesis markers. Results: Network pharmacology identified TP53, AKT1, MYC, and VEGF as core therapeutic targets of DBD. Conclusion: Our findings indicate that angiogenesis serves as a core mechanism driving NNK-induced lung tumorigenesis in mice. DBD attenuates tumor growth primarily by inhibiting HIF-1α/VEGF-mediated angiogenesis, with complementary contributions from restored immune homeostasis and ameliorated hypoxia.
