Fig.2

Fagan’s nomogram. Fagan’s nomogram shows the posterior probability of poor treatment outcome after incorporating AST/ALT into CURB-65 in CAP patients with T2DM (A) and in all the CAP patients enrolled in this study (B). The left axis represents the pre-test probability, which varies across cohorts. The middle axis indicates the positive and negative likelihood ratios, while the right axis shows the post-test probability. To calculate the risk (post-test probability, %) of poor prognosis for an individual patient, a straight line can be drawn through the pre-test probability and the positive (blue line) or the negative likelihood ratio (red line) to yield a post-test probability. All corresponding data are listed below
