Recently, the unified model based multifactor dimensionality reduction method (UM-MDR) has been proposed to unify the significance testing with the MDR algorithm within the regression model framework, in which neither cross-validation nor permutation testing are needed. In this paper, we proposed a ...
2.Utilize the regression analysis to analyze multiple factor and to establish prognosis index(PI) model according to the analytic result.并对包括cox-2在内的可能影响膀胱移行细胞癌术后预后的多因素进行cox回归分析,筛选出危险因素,并计算出患者的预后指数。 6)Multi-factor多种因素 1.ResultsMulti-factors ...
Using stepwise regression based on the AIC, independent prognostic factors were identified, including MPIS, differentiation, and TNM stage (Table2). In the discovery set, we built the full model incorporating the above independent factors, and established the clinical model incorporating two clinicopath...
Cox proportional hazard regression model including as a factor and (d) gastric cancer according to each aetiological factor in the constructed multi-factor weighted Cox proportional hazard regression model and estimating an individual's probability of developing gastric cancer based on the risk estimate....
Cox proportional hazard regression analyses were applied to evaluate the relation between biomarkers and the occurrence of all-cause mortality or non-fatal myocardial infarction (MI). 1090 patients with NSTEACS. All-cause mortality and non-fatal MI during a median follow-up of 4 years. The ...
Univariate and multivariate Cox regression were conducted to identify independent risk factors for recurrent hemoptysis. The Kaplan-Meier curves was conducted to compare recurrent hemoptysis-free rates after BAE for non-PA, non-MDR-PA, and MDR-PA.A total of 432 patients were included. 181 (41.90...
Univariate and stepwise multivariate Cox regression were used for feature selection. A nomogram for 1-, 3-, and 5-year postoperative survival rates was constructed accordingly. Performance assessment included Harrell's concordance index (C-index), receiver operating characteristic (ROC) curves and ...
We explored the clinicopathological features associated with ctDNA RAS status and the factors related to anti-EGFR mAb rechallenge efficacy in multivariate Cox proportional hazard regression.The incidence of RAS MT in ctDNA was 40.5% (30/74), which was associated with primary tumor resection ( P ...
Cox regression analysis was used to identify factors associated with discontinuing second-line biologics. Only elements with a p value less than 0.1 in univariable analysis were included in multivariable analysis, and a p value < 0.05 was considered statistically significant. Statistical analysis was ...
