Significant level of steps			P=0.008	0.002 = P	0.005 = P	0.064 = P	0.164 = P	0.084 = P	0.147 = P
Significant level within the intervention group			0.001>P
Significant level within the control group			0.001>P
Significant level between groups			0.001>P

The measured steps are as follows: the time of entry into the ICU, the first respiratory drive, the family entrance, 20 min after the family presence, and 1 h after the presence of the family member, the time of extubation, and 1 h after extubation
