Proportion of the effect of frailty on mortality mediated by different complication subtype definitions. Included are posterior distributions for each parameter, along with a dot (representing the median value), a thick bar (50% credible interval), and thin bar (95% credible interval). Credible intervals were based on the highest density interval of the posterior distribution. Because multiple mediators were included in this analysis, the values should be interpreted as relative strengths, not absolute values (as medians can, and do, sum to greater than 1). The dashed vertical line is the null value; therefore, credible intervals overlapping this line are less than 95% probable to mediate an effect.
