The POEM “Positive Feedback Is Effective for Decreasing Stuttering” (February 1, 2006, page 524) contained an error in the last full paragraph of the right-hand column on page 524. The last sentence of this paragraph incorrectly listed the number needed to treat as 7.8; 95% confidence interval (CI), 6.9 to 20.0. The sentence should read have as follows: “Significantly more children in the treated group decreased to a stuttering rate of less than 1 percent of syllables compared with children in the control group (number needed to treat = 2.3; 95% CI, 1.4 to 14.5).” The online version of this article has been corrected.
