Missing Journal Club Designation. In the table of contents and in Clinical Trials, the article titled “Sensitivity and Specificity of a Point-of-Care Matrix Metalloproteinase 9 Immunoassay for Diagnosing Inflammation Related to Dry Eye” by Sambursky et al, published in the January issue of JAMA Ophthalmology (2013;131[1]:24-28), was missing the designation as a Journal Club article. Consequently, at the end of the “Acknowledgements,” the following entry should have appeared: “ Online-Only Material: This article is featured in the JAMA Ophthalmology Journal Club.
