Just wanted to share another video from ECHO Research <http://www.echokt.ca/> and the Alberta Research Centre for Health Evidence (ARCHE) <https://www.ualberta.ca/pediatrics/pediatric-research/affiliated-research-units/alberta-research-centre-for-health-evidence-arche/index.html> at the University of Alberta. These videos are part of a social media campaign to increase public awareness and understanding about what health research is. This is one of the videos of a 5-part video series called "Understanding Health Research" that is being promoted throughout November on social media. The video titled “Why Do Health Recommendations Change?” explains why health recommendations change over time, and how it's a sign of moving forward. *Visit here <http://bit.ly/EvidenceEvolves> to watch the video and please retweet/share <https://mobile.twitter.com/Cochrane_Child/status/1328730880978849793> it on social media.* To manage subscriptions/passwords, or view archives, go to http://listserv.yorku.ca/archives/click4hp.html .
