Non-factual videos were found to have lower CSS (mean difference (MD): −1.15; 95% CI −2.04 to −0.26; p=0.008), mDISCERN (MD −2.34; 95% CI −2.99 to −1.69; p<0.001) and mJAMA (MD −1.11; 95% CI −1.61 to −0.62; p<0.001) scores compared with factual videos.
Bolded p values are significant (p<0.05).
Data are presented as (N (%)) or mean±SD.
*P values represent a comparison of the number of non-factual videos from each source to government and professional videos.
