what are these p numbers and what do they mean based on the article with these numbers?

In statistics, some people incorrectly believe that the P value is the level of significance. However, alpha is the level of significance. Alpha is usually set to 0.05. This represents +/- two standard deviations from the mean in a standard distribution. The region beyond alpha is known as the critical region. A calculated statistic must fall in the critical region in order for the data, i.e., the sample mean, to be considered significant. In effect, < 0.05. Thus, a sample mean falling in 95% of the center area under the standard distribution is not significant while if it's in 2.5% at either end then it's significant. That said, P is the probability of obtaining a sample mean with a given population mean. In general, a lower P value is better. However, nearly all journal articles incorrectly use P values to express the idea that some data is more significant than other data, i.e., P <0.01 vs. P<0.0001 etc. Any P value less than alpha, or < 0.05, is significant.

Hopefully its simply marketing hype, or a rubber stamp issue.Different sources of D-Biotin currently exist for low-dose food supplements or veterinary use. DSM is currently producing the only pharmaceutical grade biotin having a CEP (Certificate of suitability of Monographs of the European Pharmacopoeia) suitable for chronic administration of high doses in patients.
