Errors in Abstract and Table 2. In the Study by Ryan et al titled “The Effect of Narrowband UV-B Treatment for Psoriasis on Vitamin D Status During Wintertime in Ireland,” published in the August 2010 issue of the Archives (2010;146:836-842), the first sentence of the “Results” section in the abstract should have read as follows: “Levels of serum 25(OH)D increased significantly (P < .001) from a median (range) of 23 (9-46) ng/mL at baseline to 51 [rather than 59, as given in the originally published article] (32-112) ng/mL at the end of NB–UV-B treatment compared with no change in the control group.” In Table 2, the final 25(OH)D level for the treatment group and the baseline 25(OH)D level for the control group were transposed and should have read 51 (32-112) and 13 (7-33) ng/mL, respectively.
