Here's the letter my co-authors had sent on that now retracted "cloth masks don't work" study (42 citations on Google Scholar already and countless news articles). Note: it was always so underpowered that it was fairly useless even without these errors.https://twitter.com/jeremyphoward/status/1267832478502391813 …

Again, folks, errors happen. But there really is a robust meta-review process among the scientific community right now—from preprint to peer-review to post peer-review. It's a real community working hard, debating, checking. Reporting should include this.https://twitter.com/CT_Bergstrom/status/1267659926811230209 …

Carl T. BergstromVerified account @CT_BergstromRemember that paper that said masks don't work because if you cough through them on a petri dish, some viral RNA gets through? Retracted because the authors didn't understand their own methodology and drew meaningless conclusions. h/t@dylanhmorris https://www.acpjournals.org/doi/10.7326/L20-0745 … pic.twitter.com/5YnVratp0WShow this thread2 replies 28 retweets 108 likesShow this thread -
Here's our own preprint on masks for reducing *transmission* of COVID, now in version two because we got a lot of useful feedback to version one and systematically went through and updated our paper with clarifications, additions and fixed a few errors! https://www.preprints.org/manuscript/202004.0203/v2 …pic.twitter.com/m9HyorltZp

Media: please plug into the scientific community and its current pre- *and* post- peer review process before running with the headlines. Remember my warning about the Lancet study on HCQ harms? Even more questions about it now. Wait. For. RCTs. To. End.https://twitter.com/zeynep/status/1264671101587804172 …

zeynep tufekciVerified account @zeynepPeople should stop making scary declarations about HCQ. As of yet, there is no evidence of harm. The observational studies are good to have, but there are actual randomized trials going on. They urgently checked and found *no* indication of harm, yet, and the trial is continuing. https://twitter.com/rfsquared/status/1264638707916832768 …Show this thread3 replies 11 retweets 56 likesShow this thread -
Article with many questions about that observational Lancet study alleging harms from hydroxychloroquine. This doesn't mean there are no harms, but a randomized trial was stopped and checked and none was found. It also doesn't mean it's beneficial. Wait!https://www.sciencemag.org/news/2020/06/mysterious-company-s-coronavirus-papers-top-medical-journals-may-be-unraveling …

Despite many alarmist headlines and the polarized social media chatter about hydroxychloroquine, many scientists from top institutions questioned that Lancet study because.. well, there were questions. There's a process. It is messy but it does bend toward empirical validity.

Yes, it's hard to stop him from hijacking people's minds. But important to try. Recent reporting and social media reaction on hydroxychloroquine has been less than stellar, and has actually harmed our ability to understand potential harms or benefits.https://twitter.com/trengarajan/status/1268162690570051584 …

Here we go. That Lancet study on hydroxychloroquine may well be retracted. Folks, many scientists *warned* about this study as soon as it was published. Peer review catches most crap, and we also catch what gets through. Wait. Listen. Don't sensationalize. https://www.theguardian.com/world/2020/jun/03/covid-19-surgisphere-who-world-health-organization-hydroxychloroquine …

Besides the fact that the Lancet HCQ study was observational with glaring problems of controlling for severity, a randomized trial on HCQ was unblinded as a result and found no harms. That's a very loud signal. I tried to warn and got a lot of push-back.https://twitter.com/zeynep/status/1264671101587804172 …
