Accuracy of age-predicting models. The biological age estimation according to deep convolutional neural network CNN_Age (A), the multivariate regression REG_Age (B), and the unsupervised PCA_Age (C) models. The solid lines and the transparent ± standard deviation bands are color coded as green, blue, and red, representing the whole population, the patients diagnosed with diabetes by a doctor, and individuals with self-reported high blood pressure, respectively. All the calculations were produced using the NHANES 2003–2006 cohort wearable accelerometers data, comprising one-week long activity tracks (1 min⁻¹ sampling rate).
