In the article entitled "Rigor of Research Methods in Studies of the Effectiveness and Safety of Cataract Extraction With Intraocular Lens Implantation," published in the February 1994 issue of the Archives (1994;112: 228-238), an incorrect page number was given in reference to another article in the same issue of the Archives. On page 231, in the middle of the first paragraph in the left-hand column, the reference line should have read, "See also page 239."
