From: Characteristics of the antibiotic regimen that affect antimicrobial resistance in urinary pathogens
Predicted antimicrobial resistance index (ARI) as reported for Escherichia coli isolated from the urinary tract of retired patients (Belgium, 2005) when varying the number of preceding prescriptions (1–30) for male and female patients. Estimates were obtained from a generalized estimating equations (GEE) model (fitted for a patient that was alive at the end of the study and was tested 33 (median) days after the most recent prescription in reference laboratory 15)
