The units for DHEA-S in μg/mL used in the manuscript were in error. The units throughout the manuscript for DHEA-S should have been μg/dL, as was used in Fig. 2 of the manuscript. DHEA-S controls from the manufacturer were supplied in μg/dL units and yielded assay results in the reportable range of μg/dL.
