Yes, I followed the ones posted. None of them say the opposite, they all leave out the results from the lidded flushes. And someone else posted a paper that showed that although lid closed produced fewer particles, they were larger, and lasted longer, so flushing lid closed was not particularly more hygienic.

That's not a research article, it's an opinion piece with no published data and no references.
here's a real research article that found lidded flushing still produced large aerosolized droplets on flushing:

I'm not sure how this qualifies as being any better, I read this one previously and found it to be lacking in actual data information. It makes claims but literally anyone can write whatever they want on the Internet. It's not enough data and not clear on how they actually measured or how many measurements they took
