Next of kin’s age, IES-R score, family satisfaction score, patients’ age, duration of mechanical ventilation, and length of stay are expressed as median and interquartile range; the Acute Physiology and Chronic Health Evaluation II (APACHE II) score and the Simplified Acute Physiology Score II (SAPS II) are expressed as mean and standard deviation
