Author Correction: The effectiveness of public health advertisements to promote health: a randomized-controlled trial on 794,000 participants

摘要

In the original version of the published Article, there was an error in the caption to Table 1 which stated “None of the differences are statistically significant (χ2, two-sided, p  0.05)”. This has been changed to “The 18–24 year old are over-represented in the all user treatment population, while the 50–64 year old are underrepresented in both tracked and all user population, p-values were 0.05 for age groups and gender.” This has been corrected in the HTML and PDF version of the Article.
