Hence, a p value is not the only form of statistical support for the model or theory being tested, and the value of a study does not depend solely on the p values found.
Physician-assessed clinical signs(SCORing Atopic Dermatitis index(SCORAD)) were reduced in both groups, but the difference between groups was reported as non-significant(no P value given).
By the time of the initial peer-reviewed report of the study, the DFS still favored the chemotherapy group(median DFS of 48 months vs. 16 months), but the P value had risen to .04.
Because superiority was not demonstrated for the first major secondary endpoint, p-values for all the subsequent major secondary endpoints were considered nominal.
In general, p values tell readers only whether any difference between groups, relationship, etc., is likely to be due to chance or to the variable(s) you are studying.
Bonferroni手順によって補正されるp値は、次式で定義される:。
The corrected p-value according to the Bonferroni procedure is defined by.
調整されたp値は、通常、未調整のp値より正確です。
The adjusted p-value is usually more accurate than the unadjusted p-value..
P値は、確率です。
P is a probability.
満たさない場合、計算されるp値は正確なp値の上限を示します。
If not, the calculated p-value represents an upper bound for the exact p-value..
調整済みのp値は通常、調整されていないp値よりも正確です。
The adjusted p-value is usually more accurate than the unadjusted p-value..
この列の上を見ると、対応するp値は0.05であることがわかります。
Looking to the top of this column, we see that the corresponding p value is 0.05.
