Correction to: A smartphone app intervention for adult cannabis users wanting to quit or reduce their use: a pilot evaluation
Journal of Cannabis Research volume 1, Article number: 10 (2019)
Correction to: J Cannabis Res (2019) 1:9
Following publication of the original article (Albertella et al. 2019), the authors have flagged an error concerning the reference to the ‘follow-up Mann-Whitney U test’ in the Results section of the article.
The error is that the median values in brackets should be switched: the Action group should have the lower median value of 12.0, while the Contemplation group should have the higher value of 24.5.
NB the corresponding information in Fig. 2a is correct; the error affects just the above mentioned median values.
The authors apologize for this error.
