Analysis of NHANES 2003–2004 with varying nonwear allowance.

Number of participants with ≥ 1 valid day and ≥ 4 valid days and the average counts-per-minute for each after applying NCI nonwear classification algorithm to the NHANES 2003–2004 PAM dataset and redesignating nonwear time with T or more counts-per-hour as wear time. A valid day is defined as ≥ 10 hours of wear time in a 24-hour day, beginning at midnight. Results are shown with difference and percent difference from baseline in parenthesis.
