Just like the DNA methylation data is perhaps not available today inside the possible cohort communities therefore the HFmeRisk model consists of four medical keeps, you can find already zero compatible datasets in public databases which could be studied once the additional assessment set. To advance show the fresh new validity of your HFmeRisk model, we analyzed the new design using thirty-six patients that has set up HFpEF and you will dos samples who did not have HFpEF immediately following 8 years about Framingham Center Investigation cohort but did not can be found in the newest HFmeRisk design, and received an AUC out-of 0.82 (Extra file step 3: Fig. S1). We made an effort to reveal that the predictive fuel of HFmeRisk design having HFpEF try reliable of the researching 38 samples.

In addition, we compared the performance of the HFmeRisk model with nine benchmark machine learning models that are currently widely used (Additional file 1: Materials and Methods Section 2). Although there were slight differences among their AUCs (AUC = 0.63–0.83) using the same 30 features, the DeepFM model still achieved the best performance (AUC = 0.90, Additional file 3: Fig. S2 and Additional file 2: Table S3). We also used the Cox regression https://hookupfornight.com/teen-hookup-apps/ model, a common model for disease risk prediction, for comparison with machine learning model. If the variables with P < 0.05 in univariate analysis were used for multivariate analysis, the screening of variables from the 450 K DNA microarray data works tremendously, so we directly used the 30-dimensional features obtained by dimensionality reduction for multivariate analysis of cox regression. The performance of the models was compared using the C statistic or AUC, and the DeepFM model (AUC = 0.90) performed better than the Cox regression model (C statistic = 0.85). 199). The calibration curves for the possibility of 8-year early risk prediction of HFpEF displayed obvious concordance between the predicted and observed results (Additional file 3: Fig. S3).

The overall MCC threshold should be set to 0

To evaluate if other omics research could also expect HFpEF, HFmeRisk are compared with most other omics designs (“EHR + RNA” model and “EHR + microRNA” model). To own “EHR + RNA” model and “EHR + microRNA” design, i made use of the uniform function possibilities and you can modeling method with the HFmeRisk design (Extra document step 1: Material and methods Parts 4 and you may 5; More document 3: Fig. (περισσότερα…)
