Be careful with any MSM "studies". Either post/read the study itself or ignore it altogether. According to MSM studies over the years, cancer has been cured a million times, chocolate causes cancer and cures cancer, wine does the same, and vaping is more dangerous than smoking. And generally a single study doesn't mean much, you need multiple studies confirming the same thing before it should be taken seriously. And if a study isn't cited by other studies, the consensus is that it's a worthless study. See a lot of feminist "studies" that have been cited zero times.
