Summary ROC plot of SEN and SPE of serum GM and BAL-GM.
(Dotted ellipses around the spots represent the 95% CI around the summary estimates. The diamonds and rectangles represent individual studies and size of the diamonds/rectangles is proportional to the number of patients included in the study).
