Values are means ± SDs, n = 22 per group. Physical activity indices featured in partial least squares regression modeling weight loss at a VIP cutoff of 1.5. Pairwise comparisons of means were conducted on variables with a significant responder group fixed effect. Means without a common letter differ with the use of Tukey’s honestly significant difference tests. AC, activity count; VIP, variable importance in projection.

Subject identification was input as a random effect. Statistical significance was set at P ≤ 0.05. No physical activity indices were found to be significant at α = 0.05 after false discovery rate correction (38).
