A case-control study of prosthetic implants and selected chronic diseases in Medicare claims data
S Greenland, WD Finkle - Annals of epidemiology, 1998 - Elsevier
PURPOSE: In an exploratory case-control study of a private insurance-claims database,
Greenland and Finkle observed associations of certain prosthetic nonbreast implants with
certain connective-tissue and neurologic conditions. We wished to test these associations
using the same design with new data. METHODS: We examined these associations in a
case-control analysis of Medicare claims data. To control for possible confounding effects of
surgery, our analysis examined nonimplant surgeries of severity similar to implant surgeries …
