aProblem related to the definition of variables and its application (e.g., chronic diseases, type of admission, sustained haemodynamics, GCS in aphasic stroke).
bMathematical problem (e.g., oxygenation ratio, age, daily urinary output).
cInsufficient examination of the charts (e.g., erroneous exclusion of laboratory results).
dOther mechanism (e.g., insufficient available data in the chart).
