Table 2 Cross-tables and degree of agreement between the different diagnostic tests. TL = immune trypanolysis, GST = Giemsa stained thin smear, FGT = formol gel test, TL = immune trypanolysis, CATT = CATT/T. evansi, ELISA = ELISA/VSG RoTat 1.2, pos = positive, neg = negative, CI = 95 % confidence interval, k = kappa with the following interpretation of agreement: <0 = poor, 0–0.2 = slight, 0.21-0.4 = fair, 0.41-0.6 = moderate, 0.61-0.8 = substantial, 0.81-1 = almost perfect
