Leaf wetness duration in irrigated citrus orchards in the Mediterranean climate conditions por Bassimba, Daniel, Intrigliolo, Diego S., Dalla Marta, Anna, Orlandini, Simone, Vicent, Antonio

“…All the sensors and models evaluated showed a substantial strength of agreement with visual observations of LW, with area under the ROC curve of 0.89-0.93 and Cohen's Kappa index of 0.61-0.77. The RH model was recommended because of easier implementation in citrus orchards in Spain. …”

Calculation of Diagnostic Parameters of Advanced Serological and Molecular Tissue-Print Methods for Detection of Citrus tristeza virus: A Model for Other Plant Pathogens por Vidal, Eduardo, Yokomi, R. K., Moreno, A., Bertolini, Edson, Cambra, Mariano

“…The total agreement between both detection methods was substantial (Cohen's kappa index of 0.77 +/- 0.03). The diagnostic parameters of each technique (i.e., the sensitivity, specificity, and likelihood ratios) were evaluated in a second test involving 658 Citrus macrophylla nursery plants. …”

Estimation of the accuracy of two diagnostic methods for the detection of Plum pox virus in nursery blocks by latent class models por Vidal, Eduardo, Moreno, A., Bertolini, Edson, Cambra, Mariano

“…The agreement between the techniques was almost perfect (Cohens kappa index of 0.88 +/- 0.01). The diagnostic parameters (sensitivity, specificity and likelihood ratios) of both techniques were simultaneously evaluated in 2473 nursery plants by latent class models using maximum likelihood functions and a Bayesian approach. …”

Enhanced detection of Leptospira in cattle : Comparative performance of loop-mediated isothermal amplification, polymerase chain reaction and serological methods por Hamer, Micaela, Saraullo, Vanina Rosa, Esteban, Micaela, Sanchez, Maria Cristina, Brihuega, Bibiana Felicitas, Martinez, Mara Leila

“…Notably, LAMP exhibited a high diagnostic sensitivity (100 %, 95 % CI: 93.5–100 %) and specificity (95.4 %, 95 % CI: 93.2–97.0 %), outperforming lipL32 PCR in DNA detection. Additionally, Cohen’s Kappa index (0.792) indicated substantial agreement between LAMP and lipL32 PCR. …”
