Errors in Abstract, Text, and Tables in: Effect of Increasing Doses of Saw Palmetto Extract on Lower Urinary Tract Symptoms: A Randomized Trial

JAMA. 2012;307(22):2374. doi:10.1001/jama.2012.5393

Errors in Abstract, Text, and Tables: In the Original Contribution entitled “Effect of Increasing Doses of Saw Palmetto Extract on Lower Urinary Tract Symptoms: A Randomized Trial,” published in the September 28, 2011, issue of JAMA (2011;306[12]:1344-1351), errors occurred in the abstract, text, and tables. In the abstract, the 95% CI for mean AUASI score between baseline and 72 weeks for the saw palmetto extract group should have been −3.04 to −1.36. In the second paragraph of the Results section, the median pill count across attended visits should have been 97.1%. In Table 1, the range of the NIH CPSI pain scale in the Total column should have been (0-3) and in the Placebo column, it should have been (0-3). Also, the superscript “c” in the footnote should have referred to “Fisher exact test.” In the third paragraph of the Results section, the proportion of participants achieving a 3-point decrease in AUASI score at 72 weeks should have been 48.9% in the saw palmetto extract group and 52.5% in the placebo group (1-sided Fisher exact test, P = .79); and the results of the mixed models repeated measures analysis P value for saw palmetto extract vs placebo should have been .65. In Table 2, the 95% CI for mean difference in primary AUASI score for the saw palmetto extract group should have been −3.04 to −1.36. This article was corrected online.
