Journal ArticleDOI
Principles and practical application of the receiver-operating characteristic analysis for diagnostic tests.
TL;DR: The principles and practical application of receiver-operating characteristic (ROC) analysis for diagnostic tests, including meta-analysis of diagnostic Tests, correlated ROC curves (paired-sample design) and chance- and prevalence-corrected R OC curves are reviewed.
Journal ArticleDOI
Zoonosis emergence linked to agricultural intensification and environmental change
Bryony A. Jones,Delia Grace,Richard Kock,Silvia Alonso,Jonathan Rushton,Mohammed Yahya Said,Declan J. McKeever,Florence Mutua,J. Young,John J. McDermott,Dirk U. Pfeiffer +10 more
TL;DR: It is concluded that the rate of future zoonotic disease emergence or reemergence will be closely linked to the evolution of the agriculture–environment nexus, and available research inadequately addresses the complexity and interrelatedness of environmental, biological, economic, and social dimensions of zoonosis.
Journal ArticleDOI
Clinical evaluation of postpartum vaginal mucus reflects uterine bacterial infection and the immune response in cattle.
E. J. Williams,Deborah P. Fischer,Dirk U. Pfeiffer,Gary C.W. England,David E. Noakes,Hilary Dobson,I. Martin Sheldon +6 more
TL;DR: The hypothesis that clinical evaluation of endometritis reflects the number of bacteria present in the uterus, and the acute phase protein response is tested.
Journal ArticleDOI
Influence of uterine bacterial contamination after parturition on ovarian dominant follicle selection and follicle growth and function in cattle.
TL;DR: Evidence is provided for an effect of the uterus on the ovary after parturition, whereby uterine bacteria have a contemporaneous localized effect on ovarian follicle selection and subsequent growth and function, but not on initial emergence.
MonographDOI
Spatial Analysis in Epidemiology
Dirk U. Pfeiffer,Timothy P. Robinson,Mark Stevenson,Kim B. Stevens,David J. Rogers,Archie C. A. Clements +5 more
TL;DR: This book provides an overview of the use of spatial statistics in epidemiology - the study of the incidence and distribution of diseases, and describes both infectious diseases and non-infectious conditions.
