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
Objectives: Asthma is a complex inflammatory disease of the lungs marked by increased infiltration of leukocytes into the airways, which restricts respiratory function. Proliferator-activated receptor-γ coactivator-1 alpha (PGC-1α) has been recognized as an essential immunomodulator and has the potential as a novel anti-inflammatory target in asthma. The current study aims to investigate the functions of PGC-1α in ovalbumin (OVA)-sensitized asthmatic mice and underlying mechanisms. Materials and Methods: BALB/c mouse asthma model was induced by OVA Results: In the lung tissue of asthmatic mice, PGC-1α levels were down-regulated. Diff-Quik staining indicated that ZLN005 therapy on asthmatic mice reduced the number of inflammatory cells (eosinophilic granulocytes, neutrophils, lymphocytes, and mononuclear macrophages) in bronchoalveolar lavage fluid (BALF), ameliorated pathologic alterations in lung tissues. ZLN005 alleviated airway structure and inflammation, as well as down-regulating the serum immunoglobulin E (IgE), OVA-specific IgE, and T-helper 2 (Th2) cytokines (interleukin (IL)-4, IL-5, and IL-13) expression. Mechanistically, the results showed that ZLN005, through the NF-κB-p65 axis, prominently inhibited the activation of the NLRP3 inflammasome and reduced the levels of the NLRP3 downstream targets IL-1β and IL-18. Conclusion: PGC-1α agonist (ZLN005) regulated lung inflammation in asthmatic mice by inhibiting the NF-κB-p65/NLRP3 signaling pathway, supporting that ZLN005 may be a candidate for future asthma treatment.
