WebMar 24, 2016 · Except when one-sided tests are required by study design, such as in noninferiority trials, all reported P values should be two-sided. In general, P values larger than 0.01 should be reported to two decimal places, those between 0.01 and 0.001 to three decimal places; P values smaller than 0.001 should be reported as P<0.001. http://web.mit.edu/course/17/17.846/OldFiles/www/Readout.html
