Following publication of the original article [1], the following corrections should be made:

The first paragraph of the results should read:

A total of 162 patients [66 (40.7%) nulliparous and 96 (59.3%) multiparous women] were recruited (Table 1). Some of them had pregnancy-induced disorders as gestational diabetes (1/66 in nulliparous and 5/96 in multiparous women) and gestational hypertension (4/66 in nulliparous and 2/96 in multiparous women).

In Table 1, the mean cervical length measurement for multiparous women was incorrect. The corrected Table 1:

Table 1 Demographic data (162 patients)

The third paragraph of the results should be replaced with the following:

There were significant associations between cervical length and both onset of labor and mode of delivery in nulli- and multi-parous women (Chi-squared test p-value < 0.001 for all).

Table 3 shows that there was a statistically significant weak positive correlation between cervical length and gestational age at delivery in nulli-parous women.
