BP-blood pressure; HbA1c: glycosylated hemoglobin; LDL: low density lipoprotein cholesterol; HDL: high-density lipoprotein cholesterol; CSA: cross sectional area.
¥Negative values denote a decrease in the outcome measure (i.e., this is a positive effect, since a reduction in disease processes, such as lowered BP, LDL, and HBA1c, indicates an improvement in disease management).
*Further muscle measures were not entered into CMA; all values are means ± SE, taken from [17].
