ROC Curves. Smoothed (dashed lines) and not smoothed (continuous lines) Receiver Operating Characteristic (ROC) curves and Area Under the Receiver Operating Characteristic (AUROC) corresponding to the ELISA quantifications in discriminating LLIs from CTRLS and F-LLIs from HA-LLIs respectively. 95 % CI = 95 % Confidence Interval. AUROC estimates and 95 % CI refer to the two not smoothed curves
