Methylation and RNA-seq data were downloaded for The Cancer Genome Atlas (TCGA). I can see the low-quality systematic reviews and meta-analyses get published just because they have provided a significant (and also misleading) evidence and the editors always like the significant and also surprising evidence. The Cancer Genome Atlas Clinical Explorer (Stanford-TCGA-CE) aids in finding associations between genomic/proteomic features and clinical parameters, hence finding potentially clinically relevant genes. The surprising part is that the high-quality systematic reviews and meta-analyses which reject the results of the previous misleading systematic reviews or improve the previous evidence, hardly get published. Unsupervised analysis includes differential expression, PCA and clustering. To analyze the risk factors behind the lung cancer survival, this paper employs two main models: Kaplan-Meier estimator and Cox proportional hazard model [ 1 ]. Users may choose to perform various comprehensive analyses at the dataset level, including identification of highly expressed miRNAs, DE analysis between two customized groups, ROC analysis, feature selection using a machine learning algorithm, principal component analysis (PCA), and survival analysis in a TCGA project or in a circulating miRNome dataset.

KM analysis was based on individual gene expression value and survival data. Survival analysis and screening of independent prognostic factors in mutation types were conducted by Cox proportional hazards models and Kaplan-Meier methods. Two basic concepts in doing survival analysis are survival time and the event in a study. As for now, I am working on some documents and policy briefs. Once your data is on the screen, click the three-dot caret menu at the top of the column and choose 'Kaplan Meier Plot'. High CDC25C expression was more strongly associated with a worse prognosis than low CDC25C expression (P < 0.001). Public data is available through the TCGA2STAT R package, vignette.
