The integration enables you to: Save Prism files into the Online Research. Prism makes it easy to collaborate with colleagues, receive feedback from peers, and share your research with the world. A standard normal deviate ( z-value) is calculated as ln(OR)/SE, and the P-value is the area of the normal distribution that falls outside ± z (see Values of the Normal distribution table). GraphPad Prism (Version 5.04 / 5.0d and higher) integrates with LabArchives. Test of significance: the P-value is calculated according to Sheskin, 2004 (p. Where zeros cause problems with computation of the odds ratio or its standard error, 0.5 is added to all cells (a, b, c, d) (Pagano & Gauvreau, 2000 Deeks & Higgins, 2010). With the standard error of the log odds ratio being The odds ratio (OR), its standard error and 95% confidence interval are calculated according to Altman, 1991.
