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
objectiveTo investigate the anti-inflammatory effects and mechanisms of action of 4 steroidal alkaloids (ebeiedinone, imperialine, chuanbeinone, and peimisine) in Fritillaria.
methodsThis study established a lipopolysaccharide (LPS)-induced inflammatory model using mouse leukemia cells of monocyte macrophage (RAW 264.7) cells. The cell toxicity, nitric oxide (NO) release, expression levels of inflammatory factors, and expression levels of anti-inflammatory mechanism proteins and mRNA of ebeiedinone, imperialine, chuanbeinone, and peimisine on RAW 264.7 cells were detected by cell counting kit-8 (CCK8) assay, Griess assay, enzyme-linked immunosorbent assay, Western blot, and real-time quantitative PCR, respectively. An acute lung injury (ALI) rat model was established. Hematoxylin and eosin staining was used to observe the morphological and pathological characteristics of lung tissue in each group of rats. The expression levels of inflammatory factors and anti-inflammatory mechanism proteins and mRNA in the ALI rat model induced by the 2 alkaloids (ebeiedinone, peimisine) were detected.
resultsThe 4 alkaloids reduced the release of NO, downregulated the expression of pro-inflammatory factors, regulated the expressions of the TIR domaincontaining adapter protein inducing interferon-beta (TRIF), myeloid differentiation factor 88 (MyD88), nuclear factor kappa-B (NF-κB), and mitogen-activated protein kinases (MAPKs) signaling pathways in LPS-induced RAW 264.7 cells, exerting an anti-inflammatory effect (P<0.05 or P<0.01). Ebeiedinone and peomisine improved pulmonary edema and inflammation levels, regulated the expressions of MyD88, NF-κB, and MAPKs signaling pathways in the ALI rat model, exerting anti-inflammatory effects (P<0.05 or P<0.01).
conclusionThe 4 alkaloids of Fritillaria exert anti-inflammatory effects in vivo and in vitro through MyD88- and TRIF-dependent signaling pathways, thereby protecting rats from ALI.
