^*p-value generated from a nonparametric test for trend over ordered groups, (+) relates to a positive trend over adherence categories, and (–) relates to an inverse trend over adherence categories.

Additionally, there was an inaccuracy in the description of the scoring methodology used to calculate the Healthy Nordic Food Index. It was incorrectly stated that an intake below the median is scored as zero points, and an intake at or above the median is scored as one point. The scoring was conducted such that an intake at or below the median received a score of zero, and an intake above the median was awarded a score of 1. This has now been updated (page 4 in the publication) as follows: ‘To compute the index score for each participant, the intake of each food item included in the index was divided by the cohort median to assign each participant either a score of 1 if they were above the study median, or a score of 0 if equal to or below the study median’.

The authors sincerely regret any inconvenience this may have caused.

These discrepancies do not affect any of the numerical data or the results presented in the tables. The overall results and conclusions are upheld.
