  1. BC blood culture, IFAT immunofluorescent antibody test.
  2. (a)nr: number of positive leishmaniasis diagnoses through BC or IFAT; np: number of positive diagnoses for Leishmania spp. through PCR exam; nt: total number of dogs.
  3. (b)Sensitivity estimate (% of true positives for leishmaniasis).
  4. (c)Specificity estimate (% of true negatives for leishmaniasis).
  5. (d)Accuracy estimate (% of correct diagnosis through hemoculture and IFAT).
  6. (e)Kappa coefficient of concordance.
  7. (f)Descriptive level associated with estimated kappa coefficient.
