a, b The correlation and Bland–Altman plots for the open-source dataset, where a is for systolic blood pressure (SBP) results, and b is for diastolic blood pressure (DBP) results. c, d The correlation and Bland–Altman plots for the self-collected daytime dataset, where c is for SBP results, and b is for DBP results. e, f Mean absolute error (MAE) for different blood pressure levels before and after personalization, where e is for SBP results, and f is for DBP results. The blue line indicates the number of samples, while the box plots indicate absolute errors. Error bars represent the range of data within 1.5 times the interquartile range (IQR) from the first quartile (Q1) to the third quartile (Q3). g, h The distribution of MAE of all subjects at different BP change intervals, where g is for SBP results, and h is for DBP results. The red line indicates MAE = 7 mmHg. SD is the standard deviation of mean error.
