Erratum

After publication of the original article [1], the author noticed some errors to the article [1] which are included in this erratum. All errors reported in this erratum have been updated in the original article [1].

In the ‘Results’ section of the article Abstract, the sentence “Entropy was associated with a decreased risk of breast cancer” should be "Entropy was associated with an increased risk of breast cancer”. In the same section, the variables "FD_TH10", "FD_TH15", "FD_TH60", "FD_TH85", "FD_TH75", and "FD_TH75" should include an additional underscore so they are presented as: "FD_TH_10", "FD_TH_15", "FD_TH_60", "FD_TH_85", "FD_TH_75", and "FD_TH_75", respectively. All variables should be italicized.

In the section entitled ‘Breast texture measurements’, the sentence “the image with only constant grayscale pixels has Energy equal to 0" should state "the image with only constant grayscale pixels has Energy equal to 1".

In the ‘Results’ section of the article [1], the variable “FD_TH_75” included in sentence: “The top left and bottom left images show a top 20th percent tile value of FD_TH_75” should be included in italics.

In the ‘Abbreviations’ section, “BGTDM” should be "NGTDM". The correct version of the ‘Abbreviations’ is included in this erratum and has been updated in the original article [1].

In Table 1, in the column “Texture feature name”, the names of variables should be in italics. In addition in Table 5, in the column “Feature”, all variables should also be included in italics. The revised versions of Tables 1 and 5 are included in this erratum and have been updated in the original article [1].
