Use ROC analysis to evaluate the diagnostic efficacy of NLR in distinguishing FIC cats from healthy cats

Feline idiopathic cystitis (FIC) is a common chronic cystitis disease in cats. At present, the disease is mainly excluded by evaluating the results of blood, urine and imaging examinations of diseased animals. There is still a lack of clear and objective indicators for the diagnosis of FIC in clinical practice. In this study, the correlation between NLR and FIC was analyzed by collecting the complete blood count data of FIC cats and healthy cats.
