Abstract:
Among the many symbols that appear in the medical literature, few have received as much attention as the letter 'P'. It is printed in almost every table, discussed in every result section and often treated as the final word in the interpretation of scientific findings. In reality, the P-value is neither over-rated nor under-rated. It is simply misunderstood. It is an important tool, but it is not the main factor that determines the value of a study. What matters is not the number itself, but how we think about it and what it truly represents. This manuscript revisits the 'value' of the P-value in reproductive medicine.

Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
