Table 4 Percentage of missingness at the four time points following ICU admission

From: A prediction model for good neurological outcome in successfully resuscitated out-of-hospital cardiac arrest patients

Variables Hour 1 Hour 12 Hour 24 Hour 48
Mean MAP 11.2% 7.6% 9.5% 23.2%
Mean BIS 34.6% 35.2% 38.1% 46.3%
Absence of BIS 0 33.6% 26.7% 27.6% 25.3%
Mean SvO2 / 21.9% 21.0% 25.3%
NSE / / 26.7% 27.4%
Creatinine 8.4% 2.9% X 9.5%
Lactate 8.4% X X 4.2%
Mean SctO2 X X X 21.1%
  1. Creatinine and lactate value at hour 1 had the similar percentage of missingness across all time points (both with 8.4%). Missing variables with less than 5% of missingness were initial haemoglobin (1.0%), diabetes (1.9%), witnessed arrest (2.8%) and initial rhythm (3.7%)
  2. / variable not included in the respective model
  3. X no missingness
