Fig. 2From: Interaction between acyl-ghrelin and BMI predicts clinical outcomes in hemodialysis patientsInteraction between BMI and acyl-ghrelin (AG) for explaining all-cause mortality (a) and CVD mortality (b). The patients are divided into four groups according to the median values of AG and BMI. The data are crude (unadjusted) incidence rates of all-cause and CVD mortality.
