In Table 2 of the above-listed article, column units were incorrectly placed. In the third column (underneath “Cells in GCL”), the unit “μm” should not be present; instead, the units should appear in the sixth column directly below “Whole retina.” The corrected table appears below.

A change has been made to the first paragraph of the results section of the above-listed article. The second sentence, beginning “In brief, plasma DHEA-S concentration…” should be worded as “In brief, the plasma DHEA-S concentrations prior to randomization did not differ in the elderly men (0.67 ng/ml [interquartile range 0.50–1.20] vs. 0.63 ng/ml [0.37–0.97]) and elderly women (0.32 ng/ml [0.30–0.43] vs. 0.38 ng/ml [0.30–0.53]) treated with placebo or DHEA-S. Two years of treatment with DHEA-S resulted in an increase in DHEA-S concentrations to 3.81 ng/ml (3.30–5.08) and 4.21 ng/ml (3.28–4.89) in the elderly men and women, respectively, whereas DHEA-S concentrations remained unchanged during 2 years of treatment with placebo (0.60 ng/ml [0.43–0.90] and 0.30 ng/ml [0.30–0.38]).”
