Web7.7.7.2 Obtaining standard errors from confidence intervals and P values: absolute (difference) measures If a 95% confidence interval is available for an absolute measure of intervention effect (e.g. SMD, risk difference, rate difference), then the standard error can be calculated as SE = (upper limit – lower limit) / 3.92. Webthe number of standard errors that b differs from a slope of zero: 1 2 2 r n r s b t b − − = = (19) and then use the t-table to evaluate the α for this value of t (and n-2 degrees of freedom). The uncertainty in the elevation of the regression line at the mean X (that is, the uncertainty in Y‹ at the mean X) is simply the standard error
