Table 4 Linear regression models to predict daily total activity counts by time spent in moderate- and vigorous-intensity physical activity and wear time

From: A closer look at the relationship among accelerometer-based physical activity metrics: ICAD pooled data

  Model 1 Model 2 Model 3
R 2 0.832 0.836 0.949
   Estimate (99% CI)  
Intercept 134,711 (162,594, 166,828) 87,797 (78,716, 96,877) 164,769 (163,602, 165,936)
MVPA, minutes/day 5279 (5239,5318) 5257 (5218, 5296) 5280 (5258, 5302)
Wear time, minutes/day 100 (89, 112)
LPA, transformed minutes/day* 664 (657, 672)
  1. *Standardized residuals of LPA were created by regressing MVPA on LPA. The standardized residual variable was used for regression modeling and the parameter estimate was transformed to express it in LPA minutes/day
  2. CI, confidence interval; MVPA, moderate-and vigorous-intensity physical activity
