Fig 1 Blood propofol concentration in μg ml−1 against the propofol final dose rate in mg kg−1 h−1. The black lines are the regression lines with the 95% confidence limits. The grey lines are taken from our propofol only study.1 British Journal of Anaesthesia 2004 92, 25-32DOI: (10.1093/bja/aeh007) Copyright © 2004 British Journal of Anaesthesia Terms and Conditions
