政府支助的研究表明疫苗的确对女人例假有影响

但是这个研究说对例假的影响平均只有一天,呵呵,但是看论文里的数据图的话很多人可不止一天,为何只讲average?
And many people did notice changes to their menstrual cycles.  found numerous reports of unusually heavy flows and even breakthrough bleeding among some people who hadn't menstruated in years.
 Looking at data from 3,959 individuals, they were able to see a small shift in the time between bleeding. "We see a less-than-one-day change in their menstrual cycle length with vaccination," Edelman says.
"It's really nothing to get alarmed about," Bianchi says. Nevertheless, she adds, it does prove that the vaccines are affecting menstruation independently of other possible factors such as pandemic stress. "I think the beauty of the study is that it does affirm what individuals were reporting," she says.
Bianchi says that the NIH should have more data on how vaccines alter menstruation in the near future. Last summer, the agency funded five studies including Edelman's work, and the results of the other researchers should provide more data. Bianchi hopes that the additional research can look at a more diverse population than those that use the app, and also start to nail down other reported side-effects, including heavy periods and breakthrough bleeding.

很久不来例假和例假延长很多正负抵消也可造成很小的平均值,只讲平均值纯粹就是在耍流氓

不是只有report平均值啊,还有比如置信区间:first dose 0.71 day-increase, 98.75% CI 0.47–0.94; second dose 0.91, 98.75% CI 0.63–1.19); 多大事啊……

关键没打疫苗的对照组也有不少人例假变长变短的,多常见啊

嗯,你去跟鲜花版上那些说自己大姨妈严重紊乱的姐妹们说多大点事啊,继续一针针扎下去吧

它这个study power 太高了99%,样本量大,一点点差异也能统计显著。他们自己说得挺好:Although statistically significant, the overlaid histograms show a cycle length change distribution in vaccinated individuals that is roughly equivalent to that in unvaccinated individuals。并且里面有三四百人是在一个月经周期内打了两针疫苗,所以对月经周期的影响比较大。去掉这部分人之后就和对照组更加没有差异了。

这种论坛上说的个体数据点无法验证,没有任何study design 可言。怎么放着几千人有对照组的cohort的multi variable分析结果不看,看华人论坛上收集数据自己分析吗?

所以你在说人家自己不知道自己的大姨妈正常不正常?都在撒谎?呵呵
你没看这个研究人员说需要更多数据吗?她这点儿人是怎么选的你又都知道了?我看到的可不只是华人上很多姐妹们在抱怨还有其他很多论坛上的人也在抱怨,这篇报道也提到有做survey很多人都有大姨妈的问题,如果不是抱怨有问题的人够多NIH会砸钱去让人做研究?所以这些数据都不可信只有这个4000人(其中还有1500多人是没打疫苗的)的数据可信对吧?
可樂爆米花
我打完疫苗後大姨媽週期也變了,之前週期滿亂的,現在竟然有規律了,。

所以只要大家以后别在一个例假周期里打2针就没事了对吧?你咋不想想这研究的确证明了疫苗会影响女性生殖系统?这点研究人员也承认了的确有影响虽然根据他们这个研究来看影响也许不大,但是没人有预见到,这就是因为疫苗没有经过系统的研究时间太短造成的。她也说需要更多更广泛的数据。后边还要研究疫苗对heavy periods and breakthrough bleeding的影响,你这么急着下结论真的好吗?

你这种的可以考虑继续把疫苗打下去,哈哈
