Errors in Byline, Text, and Data in: Retrospective Analysis of the Association Between Demodex Infestation and Rosacea

Arch Dermatol. 2010;146(12):1412. doi:10.1001/archdermatol.2010.374

Errors in Byline, Text, and Data. In the Evidence-Based Dermatology: Review article titled, “Retrospective Analysis of the Association Between Demodex Infestation and Rosacea,” by Zhao et al, published in the August issue of the Archives (2010;146[8]:896-902), several errors occurred. In the byline on page 896 and in the correspondence in the right-hand column on page 901, the first author's name should have read as follows: Ya E Zhao, MPH. On page 897, right-hand column, “Sensitivity Analysis” subsection of the “Methods” section, the sentence should have read as follows: “Four approaches were applied to identify the sensitivity of the studies: we compared the pooled effect sizes (1) with different statistical models; (2) of Chinese- and English-language articles; (3) before and after excluding studies of small sample size; and (4) of studies using the cellophane tape method, skin pressurization, and skin surface biopsy.” Beginning with the third sentence of the “Sensitivity Analysis” subsection of the “Results” section, the text should have read as follows: “Twenty-eight of 48 articles included had a sample size smaller than 40 (OR, 6.96; 95% CI, 3.69-13.15). After these articles were excluded, the pooled OR of the remaining ones was 8.42 (95% CI, 5.49- 12.90) (Figure 4), which was not significantly different from that of 7.57 (5.39-10.62) in the pre-exclusion meta-analysis. The ORs of studies using the cellophane tape method13,15-18,20,21,23-26,28,30-32,34-36,39,40,42,49 (OR, 9.29; 95% CI, 5.60-15.40), skin pressurization technique10,22,37,38,43-48,50-56 (5.24; 2.85-9.63), and skin surface biopsy4,7,9,14,19,27,29,33,41 (8.87; 3.28-24.01) were coincident.”
