Response rates ? an evolution

Cancer Chemotherapy and Pharmacology, 1994
The documented frequency of response of cancers to common chemotherapy agents and combinations appears to have decreased over the decades. Multiple reasons exist for this decline including: changes in eligibility and evaluability criteria; changes in the type of patients entered onto trial; and, altered criteria for response and methods for response ...

Physiology of Rate-Responsive Pacing

Cardiology Clinics, 1992
The search for a pacemaker that accurately and easily mimics normal physiology is a continuing effort. There have been many achievements in the past, including sensing of the pacing chamber and programming of the pacing rate, sensitivity, and output. Present pacing developments include atrioventricular synchrony and rate adaptiveness.

Response rates for surveys of chiropractors

Journal of Manipulative and Physiological Therapeutics, 2004
Survey response rates may vary by type of practitioner studied and may have declined over time. Response rates for surveys of complementary practitioners have not been studied.To describe the response rates in published surveys of chiropractors and explore for secular trends in response rates and for methodologic and geographic correlates of response ...

Response Rates

The Cancer Journal, 2009
A main criterion to identify activity in phase II studies is the response rates achieved in a well-defined subset of patients. The response could be defined as a measure of tumor shrinkage. For 30 years, metric methods have been used to assess this response.
