Posterior density distribution plot (left) and Funnel plot (right) for the evaluation of potential bias in diagnosing acute kidney injury with the level of urine kidney injury molecule 1. The posterior density distribution plot displays the consistency of outcomes; the closer the peak is to the coordinate (1, 1), the more consistent the outcomes are (left). In the funnel plot the X-axis represents the diagnostic odds ratio and the Y-axis shows the index of precision of the diagnostic odds ratio (right)
