An article in The Journal of Clinical Endocrinology and Metabolism [Simultaneous and Continuous 24-Hour Plasma and Cerebrospinal Fluid Leptin Measurements: Dissociation of Concentrations in Central and Peripheral Compartments (2004, Vol. 89, pp. 258265)] studied the demographics of simultaneous and continuous 24-hour plasma and cerebrospinal fluid leptin measurements. The data follow: y BMI (kg/m2 ): 19.92 20.59 29.02 20.78 25.97 20.39 23.29 17.27 35.24 x Age (yr): 45.5 34.6 40.6 32.9 28.2 30.1 52.1 33.3 47.0 (a) Test for significance of regression using .
