Were the subjects appropriately selected?
Application to the paper: "Is it possible to exclude a diagnosis of myocardial damage within
six hours of admission to an emergency department?
Diagnostic cohort study"
BMJ 2001;323:372(18 August)
On face, would seem to be appropriately selected but process was very selective if
only 383 patients selected over a 1 year period from a busy city ER.
Who was excluded?
