- timr 6y agoThere was nothing wrong with that study that wasn't already acknowledged in the study itself. No study is perfect. If the bar for retraction of a paper is that people are misinterpreting it, then most of the studies on masks should be retracted as well.
- DeonPenny 6y agoI don't think they've interpreted anything. It falls in line with other random sampling tests. Without this data we could be making the wrong decision. Especially with countries doing widely different things. Places like Sweden, Korea, and Taiwan without quarantine and places like Germany or the US with quarantine should know which strategy works best. Which isn't at all clear right now.
- ravenstine 6y agoWhy? Even if it's not totally random(they used Facebook ads), surely the data still tells us something?
- losvedir 6y agoNot necessarily. Their population survey had 1.5% positive results. The false positive rate of the test is not known for certain but I believe the 95% confidence interval goes up to 1.7%. If that were the case, all the positive tests could even be false positives. We did learn from the study that the population rate isn't outrageously high, like 30%, but I'm not sure what more we can confidently say beyond that.
- walterbell 6y agoWhat are typical false positive rates for other tests/studies?
- DeonPenny 6y agoChina's false postives for Covid tests are 30%, I chest CT has a false positive of 6% https://www.advancedsciencenews.com/a-more-sensitive-test-for-covid-19/ https://www.advancedsciencenews.com/a-more-sensitive-test-fo.... So these test a more accurate than either of the more accurate test to diagnose Covid-19 from what I've found

- ravenstine 6y agoWouldn't that be true of anyone participating in a study? Something about this isn't making sense to me. If a study is voluntary, isn't it biased towards those who want to participate?
- pacala 6y agoWe should rather repeat that kind of study in every state, every week. Improve as we go.
