Table 3 Proportion of Variance Explained for the Outcome-Matching Models and the Proposed Calibration Models

From: Calibration of the global physical activity questionnaire to Accelerometry measured physical activity and sedentary behavior

Outcome R2 for Outcome-Matching
R2 for Final Calibration Model
Sedentary behavior 0.025 0.097
Moderate-intensity PA 0.144 0.341
Vigorous-intensity PA 0.177 0.364
MVPA 0.156 0.282
  1. PA = physical activity; MVPA = moderate- and vigorous-intensity physical activity
