What is the Value of a p Value?
The Annals of Thoracic Surgery, 2009Successful publication of a research study usually requires a small p value, typically p < 0.05. Many clinicians believe that a p value represents the probability that the null hypothesis is true, so that a small p value means the null hypothesis must be false.

p-value or P-value?—Normative Discrimination of Term “p-value” in Probability and Statistics
2021In view of the confusion problem on writing of terms “p-value” or “P-value” in the hot spot of statistical test has not been reported yet, literatures with titles including “p-value” and “P-value” in journal articles collected by CNKI in recent ten years are counted. Application status of terms writing of “p-value” and “P-value” is analyzed.

Chance of obtaining the observed result or one more extreme if one assumes that the effects of the treatments are equal; p is therefore the confidence with which the null-hypothesis is rejected and not the confidence with which one accepts that the difference is exactly zero; if p=0.05, the null-hypothesis is rejected with a probability of 5% and one ...

BMJ, 2014
Researchers investigated whether a low glycaemic index diet in pregnancy reduced the incidence of macrosomic (large for gestational age) infants in an at risk group. A randomised controlled trial study design was used. Participants were 800 women without diabetes, all in their second pregnancy, who had previously delivered an infant weighing more than ...

The value of P-values in “Table 1”
The American Journal of Emergency MedicineA traditional "Table 1" describes the characteristics of patients in a study, split by intervention, exposure, or control, not by outcome. Comparing groups in Table 1 with use of P-values is common but is a misuse of hypothesis testing that leads readers astray, often calling attention to meaningless differences while masking important ones.
