doi: 10.1101/2025.03.03.641136
Figure Lengend Snippet: Abbreviations used in this figure are as follows: raw data (raw), simple standardization (standard), quantile normalization (quantile), longitudinal ComBat (L-ComBat), proposed integration methods (INTACT and INTACT 0 ), NHANES 2003–2004 data (raw1), and NHANES 2013–2014 data (raw2). (A) Heat map of V ar 1 − V ar 2 . (B) Detection of domain effects. Left: box plots of AUC values; Right: box plots of ARI values. (C) Empirical power for testing the null hypothesis of no age effect, based on resampling 120 subjects per domain. (D) Hazard ratios and corresponding Bonferroni-corrected confidence intervals from Cox model analysis. The black solid line indicates a hazard ratio of 1. (E) Box plots of absolute mean and variance differences in summary statistics between two domains.
Article Snippet: The NHANES 2003–2004 dataset was collected using the Actigraph AM-7164, a hip-worn accelerometer, while the NHANES 2013–2014 dataset used the Actigraph GT3X+, a wrist-worn accelerometer.
