From: Validity of activity monitors in health and chronic disease: a systematic review

Study-specific correlation coefficients (r) and Fisher z-scores (diamond) between total energy expenditure estimate from the activity monitor (TEE AM ) and total energy expenditure measure from doubly labelled water (TEE DLW ). Each dot represents the z-score 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.
