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
backgroundA lot of cancers including non-small cell lung cancer (NSCLC) arise in association with chronic inflammation. In this study, Mendelian randomization (MR) and gene function analyses were integrated to address the connection between circulating inflammatory cytokines and NSCLC, and the underlying biological processes and functional significance of the correlated inflammatory cytokines.
methodsWe employed the summary statistics of 91 inflammatory cytokines and NSCLC from the genome-wide association studies. The bidirectional MR analysis was used to identify cytokines causally associated with NSCLC. The Kyoto Encyclopedia of Genes and Genomes (KEGG), Gene Ontology (GO) and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways and functional significance of the cytokines involved in the causal relationship. By using 1400 blood metabolites data and the two-step MR with an inverse variance weighted (IVW) approach, we assessed the extent to which the effect of cytokines on the risk of NSCLC was mediated by metabolites.
resultsC-C motif chemokine ligand 11 (CCL11) (P = 0.008) and CCL2 (P = 0.026) were positively correlated with NSCLC, whereas TNF-related apoptosis inducing ligand (TRAIL) (P = 0.030) and signaling lymphocytic activation molecule family member 1 (SLAMF1) (P = 0.049) were negatively associated with NSCLC. Conversely, NSCLC led to an increase of CCL13 (P = 0.025) while stem cell factor (SCF) (P = 0.009), tumor necrosis factor beta (TNF-β) (P = 0.033), and interleukin-10 (IL-10) (P = 0.042) were downregulated in NSCLC. The KEGG analysis revealed that these eight cytokines were involved in 14 distinct pathways (all adjusted P < 0.05). The GO analysis showed enrichment of specific terms associated with these cytokines (all adjusted P < 0.05). The GSEA results indicated these eight cytokines were collectively enriched in 15 biological pathways. The top 5 pathways of the ranked list are Jak-STAT, PI3K-AKT, FAK-CDC42, RTK-PI3K and PLCG-Calcineurin signaling pathways (all P < 0.05 and false discovery rate < 0.25).The two-step MR analysis showed that 1-palmitoyl-2-linoleoyl-gpc (16:0/18:2) (PC(16:0/18:2(9Z,12Z))) (P = 3.87 × 10
conclusionThe circulating inflammatory cytokines CCL11, CCL2, CCL13 and IL-10 are predominantly correlated with NSCLC, and the Jak-STAT, PI3K-AKT, FAK-CDC42, RTK-PI3K and PLCG-Calcineurin signaling pathways are closely enriched in the connection. In addition, alteration in lipid metabolism, especially phosphatidylcholine (PC) metabolism is independently linked with the risk of NSCLC induced by inflammatory cytokines.
