Okay, I need to figure out how the pathway enrichment analysis was conducted in this article. Let me start by looking through the provided text. The user mentioned that the information might be in the Methods section, but since the Methods aren't explicitly given here, I have to look for clues in other sections like the Results, Discussion, or Acknowledgments. First, the user's question is about the pathway enrichment analysis details. Let me scan through the text again. The abstract and the main body discuss the results of the analysis, like KEGG pathways such as PI3K/Akt and focal adhesion. The Discussion section mentions KEGG pathway analysis showing VEGFA enrichment in those pathways. The article states that KEGG pathway analysis was performed. But which tool did they use? Common tools for KEGG are DAVID, ClusterProfiler, or KOBAS. The text doesn't explicitly mention the tool's name. Let me check again. In the provided text, under the Results section (implied in the discussion part), they mention KEGG but don't specify the tool. The Methods section isn't present here, so maybe the authors didn't describe it in detail. Next, the version of the tool—if they didn't mention the tool itself, they probably didn't specify the version. So that would be "not described." For the gene set library, since they mention KEGG pathways, the library is KEGG. They might have used GO as well, but the text specifically refers to KEGG in the context of enrichment. The question is whether other libraries were used. The Discussion talks about KEGG, so the primary is KEGG. But maybe GO was also used? The user's example includes options like GO, so I need to check. The text says "KEGG pathway analysis showed that VEGFA was mainly enriched in...", so maybe only KEGG was used. The question is about the gene set library queried, so answer KEGG. Background gene list: Did they mention defining a background? Usually, the background is all genes in the dataset or the entire genome. The article doesn't specify, so "not described." Statistical test used: Common tests are hypergeometric or Fisher's exact. The text doesn't mention which one. Since KEGG analysis typically uses hypergeometric, but without explicit info, it's "not described." FDR correction: They might have used FDR (like Benjamini-Hochberg), but the text doesn't state this. The Results mention "enriched in the PI3K/Akt..." but not the correction method. So "not described." Wait, the user wants the answers to each question separately. Let me go through each point again. 1. Tool: The article mentions KEGG pathway analysis. DAVID is a common tool for KEGG. But since it's not explicitly stated, I have to say "not described" because the provided text doesn't mention the tool's name. 2. Tool version: Not mentioned, so "not described." 3. Gene set library: KEGG, as the text refers to KEGG pathways. 4. Background gene list: Not described in the text. 5. Statistical test: Not specified, so "not described." 6. FDR correction: The article doesn't mention controlling false positives via FDR or another method, so "not described." I need to make sure I didn't miss any part. The provided text includes the Discussion section where they talk about pathway enrichment but not the methods. Since the user said to check the Methods section but if not there, look elsewhere. Since Methods isn't present here, and the rest doesn't specify, all answers except the gene set library are "not described." 1. **What tool was used for pathway enrichment analysis?** Not described. The article mentions KEGG pathway analysis but does not specify the tool used (e.g., DAVID, ClusterProfiler, or KOBAS). 2. **Was a tool version number provided?** Not described. 3. **What gene set library was queried (e.g., GO, KEGG, Reactome, or other)?** KEGG (Kyoto Encyclopedia of Genes and Genomes) was used, as indicated in the Discussion section (e.g., "KEGG pathway analysis showed that VEGFA was mainly enriched in the PI3K/Akt..."). 4. **Was a background gene list defined for pathway enrichment analysis?** Not described. The text does not mention the definition of a background gene list. 5. **What statistical test was used for enrichment analysis?** Not described. The specific statistical test (e.g., hypergeometric, Fisher's exact test) is not mentioned. 6. **Was false discovery rate (FDR) correction used to control the number of false positives in the pathway enrichment analysis?** Not described. The article does not address whether FDR correction (e.g., Benjamini-Hochberg) was applied.
