Table 3 Acute lung injury score and apoptotic index in the supine and prone position

From: Lung and 'end organ' injury due to mechanical ventilation in animals: comparison between the prone and supine positions

  Supine position Prone position P value 95% confidence interval
Acute lung injury score 4.63 ± 0.58 2.17 ± 0.19 <0.0001 -3.9 to -1.82
Apoptotic index
   Lung dorsal 112 ± 22 45.6 ± 28 0.003 -103.6 to -29.78
   Lung ventral 80 ± 28 35 ± 22 0.02 -82.6 to -8.1
   P value 0.04 0.046   
   95% confidence interval 2.37 to 61.09 0.29 to 20.5   
Liver 56 ± 21 23 ± 10 0.05 -66.78 to -7.8.1
Kidney 31 ± 14 17 ± 10 NS  
Small intestine 22 ± 11 16 ± 11 NS  
Diaphragm 10 ± 0.5 0.5 ± 0.4 0.001 -10.6 to -9.01
  1. Acute lung injury score corresponds to the sum of the extent (score 0, 1, 2 and 3 for an extent of 0%, <25%, 25–50% and >50%) and the severity of lung injury (score 0 for no changes, score 1, 2 and 3 more severe changes). The apoptotic index was expressed as the number of apoptotic cells/bodies per 10 high-power fields.
