Can we predict upper respiratory tract infection in the winter? Suggesting a predictive diagnostic marker based on Qi-deficiency.

摘要

PURPOSE: To determine whether persons with Qi-deficiency are at high risk for upper respiratory tract infection (URTI) in the winter.DESIGN: Prospective cohort study carried out from the summer of 2007, to the winter of 2007/08, with analysis in May of 2008.PARTICIPANTS AND METHODS: Sixty-four healthy female volunteers, mean age 37.7 (SD 10.4) years, participated. Diagnostic scores of Qi, blood, and body fluids were recorded during the summer of 2007. The subjects were followed through March 31, 2008. The primary outcome measure was based on URTI, namely, both cough and fever (2s37.8degC). Odds ratios (OR) of URTI for 14 clinical signs of Qi-deficiency were estimated.
