After publication of the original article (Knudsen et al. 2016), the following corrections, and addition of citations were requested:

On page 2, Method section: subsection: Patient-reported outcome measures:

It is an 8 item test, 7 items rated dichotomously as “yes/no” responses, and one item rated on a 5-point frequency scale. A total score on the MMAS ranges from 0 to 8 points; <6 point indicates low adherence; 6 < 8 points indicates medium adherence; and 8 points reflects high adherence (Morisky et al. 2008). MMAS-8 has been translated to several languages, and many psychometric tests of the translated instrument have been performed. The scale has demonstrated good sensitivity but only moderate internal consistency. The scale has also demonstrated convergent validity with electronic measures and is a reliable tool to determine medication adherence (Morisky et al. 2008, 2011; Arnet et al. 2015; Krousel-Wood et al. 2009).
