Diagnostic accuracy of TBS-50/direct blood examination globally and stratified by age, sex, symptomatology, and eosinophilia. TP: true positive; FP: false positive; TN: true negative; FN: false negative; Se: sensitivity; Sp: specificity; PPV: predictive positive value; NPV: negative predictive value.
