Ross Naylor, MD, FRCS, Paul Hayes, MD, FRCS  Journal of Vascular Surgery  Volume 50, Issue 1, Pages (July 2009) DOI: /j.jvs Copyright © Terms and Conditions

2 Fig 1 A comparison of the numbers of postoperative emboli recorded after carotid endarterectomy (CEA), split into groups according to whether the operation finished before or after midday. The data has been log(n) transformed to enable graphic representation of the emboli numbers. Journal of Vascular Surgery  , 48-53DOI: ( /j.jvs ) Copyright © Terms and Conditions

3 Fig 2 The proportion of patients with no emboli rises after midday.
