Correction to: Human Papillomavirus and Factors Associated with Recurrence in Sinonasal Inverted Papillomas from Poland and Spain.

The original version of this article unfortunately contained a mistake. Three values in Table 1 were incorrect. In "months of recurrence", range row, the intervals should be in numbers. They should read as 3-83 instead of Mar-83, 9-83 instead of Sep-83 and 3-36 instead of Mar-36. The corrected Table 1 is given below. The original article has been corrected.
