Correction: Differences in energy and nutritional content of menu items served by popular UK chain restaurants with versus without voluntary menu labelling: A cross-sectional study.

[This corrects the article DOI: 10.1371/journal.pone.0222773.].

The number of restaurants stated to have menu labelling in store is incorrect throughout the article. The correct number of restaurants that have menu labelling in store is 14 (33%). In light of this error, the following updates should be noted:

In the Methods and findings subsection of the Abstract, there is an error in the fifth sentence. The correct sentence is: Of these, 14 (33%) voluntarily provided menu labelling.

In the Results, there is an error in the second sentence of the second paragraph. The correct sentence is: Of the 42 included restaurants with online nutritional information, 14 (33%) voluntarily provided menu labelling.

In the Results, there are errors in the third sentence of the second paragraph. The correct sentence is: Twelve of the 14 restaurants that provided voluntary menu labelling were in the top 50 by sales in 2013; 38 of the 55 functioning restaurants with functioning websites that voluntarily provided neither menu labelling or online nutritional information were in the bottom 50 by sales in 2013.

In the Discussion, there is an error in the second sentence of the second paragraph. The correct sentence is: Of 100 restaurant chains considered, 42 provided energy and nutritional information online, of which 14 provided any of this information on the restaurant menu.

In the Interpretation of findings subsection of the Discussion, there is an error in the fifth sentence of the third paragraph. The correct sentence is: It is notable that 12 of the 14 restaurants that provided voluntary menu labelling were in the top 50 by sales.

There is an error in Table 2. ‘Domino’s Pizza’ (ranked 6) should be colored orange instead of green.
