Due to the high heterogeneity of cervical cancer accelerating cancer progression, it is necessary to identify new prognostic markers and treatment regimens for cervical cancer to improve patients' survival rates. We purpose to construct and verify a risk prediction model for cervical cancer patients. Based on the analysis of data from the Gene Expression Omnibus database (GEO) and The Cancer Genome Atlas (TCGA), differences of genes in normal and cancer samples were analyzed and then used analysis of WGCNA along with consistent clustering to construct single-factor + multi-factor risk models. After regression analysis, the target genes were obtained as prognostic genes and prognostic risk models were constructed, and the validity of the risk model was confirmed using the receiver operating characteristic curve (ROC) and Kaplan-Meier curve. Subsequently, the above model was verified on the GSE44001 data validation followed by independent prognostic analysis. Enrichment analysis was conducted by grouping the high and low risks of the model. In addition, differences in immune analysis (immune infiltration, immunotherapy), drug sensitivity, and other levels were counted by the high and low risks groups. In our study, three prognostic genes including APOD, APOC1, and SQLE were obtained, and a risk model was constructed along with validation based on the above-mentioned analysis. According to the model, immune correlation and immunotherapy analyses were carried out, which will provide a theoretical basis and reference value for the exploration and treatment of cervical cancer.", "claims": [{"id": "claim-method", "statement": "Univariate Cox proportional risk regression analysis was performed on these genes using the data from the training set to verify whether these genes are risk factors.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36536343", "locator": "sections[5] \"Establishment of a risk prediction model for the prognosis of patients with cervical cancer\" paragraph 2", "quote": "Univariate Cox proportional risk regression analysis was performed on these genes using the data from the training set to verify whether these genes are risk factors."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The datasets generated and/or analysed during the current study are available in the Gene Expression Omnibus (GEO) repository, GSE63514 and GSE44001.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36536343", "locator": "sections[24] \"Availability of data and materials\" paragraph 2", "quote": "The datasets generated and/or analysed during the current study are available in the Gene Expression Omnibus (GEO) repository, GSE63514 and GSE44001."}], "state": "complete"}, {"id": "claim-target-result", "statement": "The study identified APOD, APOC1, and SQLE as prognostic genes and constructed and validated a risk prediction model for cervical cancer.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:36536343", "locator": "sections[0] \"Abstract\" paragraph 1", "quote": "In our study, three prognostic genes including APOD, APOC1, and SQLE were obtained, and a risk model was constructed along with validation based on the above-mentioned analysis."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "The study identified APOD, APOC1, and SQLE as prognostic genes and constructed and validated a risk prediction model for cervical cancer.", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:36536343"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "complete", "blocked_on": null, "description": "The GEO series accession resolves and its sample accessions are listed.
