The article “Acute Bacterial Rhinosinusitis in Adults: Part I. Evaluation” (November 1, 2004, page 1685), contained errors in Tables 4 and 6. In Table 4 (page 1688), which discussed clinical findings and imaging studies for diagnosis of acute bacterial rhinosinusitis, the sensitivity and specificity for opacification were inadvertently transposed, and should have been listed as 41 percent sensitivity and 85 percent specificity. In Table 6 (page 1689), which discussed the Berg prediction rule, the footnotes were incorrect. The online version of this article has been corrected, and the corrected Table 6 is reprinted above.

| Probability of sinusitis (%) | |||||
|---|---|---|---|---|---|
| Findings† | Sinusitis | No sinusitis | Likelihood ratio | Given 15% probability | Given 40% probability |
| 3 or 4 | 55 | 10 | 7.0 | 55 | 82 |
| 2 | 10 | 10 | 1.3 | 18 | 46 |
