How to output publishable p-value in graphs, esp. metan command, STATA 13.1

[Julien Vaucher]

Hi,

I am currently using the metan command to present results of genetic associations studies. As it happens in this kind of analyses, I get a lot of very small p-values. Is there then any way to output 'publishable' p-values with STATA, e.g. 3.30 x 10^-40 (with '-40' in superscript)? I assume this question is also valid for different graphs.

Thanks very much for your answer
Kind regards
Julien

Is this a question about how to convert 3.3e-40 to 3.30 x 10^-40 or a question about superscript in a graph? I can answer the latter.

Dear Friedrich,
Thanks for your answer. Unfortunatly I'm seeking a way to answer your former question, i.e. how to convert 3.3e-40 to 3.30 x 10-40. I currently do everything 'manually' with macros but I was wondering if anyone has found a smarter and automatic way to perform this conversion.
Best wishes
Julien
