谢谢您,他是这样问的,
Given all the comparisons that were made in the article was any form of
statistical correction applied? A significance level of P<0.05 should be
noted that
all values are uncorrected.
看不懂这个问题,

are you sure it is "correction, uncorrected"
not "correlation, uncorrelated"?

feels like he is asking unadjusted or adjusted...like adjusted for any
effect modification, confounding or precision...

When you conduct multiple comparisons, you need to adjust your p-values to
ensure the overall significance (sometimes referred to as family-wise error
rate) at 0.05 level.
Google multiple comparisons or grab an entry level applied statistics book
for more details.

ls正解.但是FWER是讲如果你的tests的purpose和content相近的情况(比如anova那种
情况下的pairwise comparison)
As noted by Hochberg and Tamhane (1987), "If these inferences are unrelated
in terms of their content or intended use (although they may be
statistically dependent), then they should be treated separately and not
jointly" (p. 6). (wiki)
如果文章当中的hypotheses不是这种情况,就没有FWER一说,FDR更适用,没有那么

Multiple testing will increase the chance of observing false results (i.e.
observing a difference purely by chance).
some corrections used to the significance level:
Bonferroni
Holms
Tukey
Dunnet
