Note: A multiple regression model was built for factors know to or that might influence the rate of fat cell lipolysis. n = 894 and 893 for lipolysis/lipid weight and/cell, respectively. r² for the model is 0.18 and 0.35 for lipolysis/lipid weight and/cell, respectively. See legend to Table 2 for details.

Abbreviations: CI, confidence interval; SE, standard error.
