Figure 2From: Trace element supplementation in hemodialysis patients: a randomized controlled trialZinc and selenium by timepoint. The left panels show the proportion of participants with low zinc status in the upper left panel and the mean serum zinc concentration of the participants in the lower left panel. The right panels show the proportion of participants with low selenium status in the upper right panel and the mean serum selenium concentration of the participants in the lower right panel. The lower panels have black horizontal lines depicting the thresholds of low element status (serum zinc <815 ug/L and serum selenium <121 ug/L). The solid line represents the control group. The dashed line represents the low dose intervention group and the short-dashed line represents the medium dose intervention group.Back to article page
