Table 4 Linear regression model for the higher NDE score

From: The effect of carbon dioxide on near-death experiences in out-of-hospital cardiac arrest survivors: a prospective observational study

Variable B Lower CI Higher CI P
Previous NDEs 6.529 0.400 12.658 0.037
pCO2 (kPa) 1.165 0.362 1.968 0.006
Potassium (mmol/l) 1.659 0.299 3.019 0.018
Constant -10.598 -17.870 -3.327 0.005
  1. Sum of squares = 331.263, df = 3, P = 0.001.
  2. CI, confidence interval; NDE, near-death experiences; pCO2, partial pressure of carbon dioxide.
