Corrigendum to “Improving adherence to endocrine hormonal therapy among breast cancer patients: Study protocol for a randomized controlled trial” [Contemp. Clin. Trials Commun. 12 (2018) 109-115]

The authors regret to inform that we will not be using the MMAS-4 scale to assess medication adherence as originally planned and included in our protocol manuscript, due to the high cost of the training required to use the instrument and potential legal issues with MMAS Research LLC. We will assess the patients’ medication adherence by using 3 questions created by the research team.

The authors would like to apologise for any inconvenience caused.
