Study-specific % mean difference (diamond) between total energy expenditure estimate from the activity monitor (TEE
) and total energy expenditure measure from doubly labelled water (TEE
). Each dot represents the mean difference of the respective study together with a 95% confidence interval (CI) and the size of the box represents the weight of the study in the meta-analysis. Weights are from random effects analysis. CV; coefficient of variation for TEEDLW. *Leenders et al. 2006 (Actigraph Model 7164); TEEAM estimated with most frequently used Freedson and Hendelman equation (walking outdoors), (not reported) data of % mean difference (±SD) between TEEAM - TEEDLW with other previously published equations can be found in the original paper .
