Fig. 3.3 Signifi cance of 8 variables as predictors of mortality, in a review of 84 reports concerning
mortality in RA, 53 cohorts presented predictors of mortality. For each variable, n = the number of
reports that included the variable, and bars indicate the percentage of those reports in which the
variable was a signifi cant predictor of mortality in multivariate analyses ( black ), in univariate
analyses ( dotted ), or not signifi cant ( white )
