Table 2 The influence of breath test performance in relation to the mean bias of the BAC and the estimated BrAC (BrAC est )

From: Assessment of the breath alcohol concentration in emergency care patients with different level of consciousness

  N Mean bias between the BAC and the BrAC est Standard deviation P-value
Forced expiration 10 −0.15 0.39  
Non-forced expiration 57 0.05 0.32 0.09
Awake 63 −0.03 0.34  
Sleeping or lowered level of consciousness 15 0.20 0.37 0.02
  1. A p-value < 0.05 was considered significant.
