Do ultrasonographic and DSCT scan analysis of single lima versus arterial T grafts 12 years after surgery?
Ultrasonography cannot distinguish between string sign and patent single LIMA or T-grafts nor demonstrate distal anastomosis patency in T-grafts 12 years after surgery.
In spite of seemingly large differences in average birthweight among maternal countries of birth (range 3290-3677 g), knowledge of the maternal country of birth does not provide accurate information for ascertaining individual offspring birthweight because of the high inter-offspring heterogeneity around country averages. Our study exemplifies the need for a better understanding of individual health diversity for which group averages may provide insufficient and even misleading information. The analytical approach we outline is therefore relevant to investigations of country of birth (and ethnic) differences in health in general.
