Cytomegalovirus reactivation and mortality in patients with acute respiratory distress syndrome	2016-03-01		.txt	text/plain	4483	200	36	Furthermore, CMV reactivation in critically ill patients has been associated with a prolonged duration of mechanical ventilation [2, 4, [9] [10] [11] [12] [13] , an increased length of stay in the ICU [3, 5, 9, 10, 13] , and excess mortality [2, 4, [7] [8] [9] . Nevertheless, it remains uncertain whether these findings imply that CMV reactivation is a truly independent risk factor with respect to these observed poor clinical outcomes because most studies that have assessed these associations did not adequately account for all possible sources of bias. Possible confounders that were screened included all patient characteristics and therapeutic interventions listed in Table 1 , and some markers of disease severity: Acute Physiology and Chronic Health Evaluation APACHE Acute Physiology and Chronic Health Evaluation, ARDS acute respiratory distress syndrome, COPD chronic obstructive pulmonary disease, ICU intensive care unit, PEEP positive end expiratory pressure, P/F partial pressure of oxygen in arterial blood to fraction of inspired oxygen ratio (APACHE) IV score, presence of septic shock, partial pressure of oxygen in arterial blood to fraction of inspired oxygen ratio, and positive end expiratory pressure (PEEP) setting.	./cache/cord-001938-n2d5fw2f.txt	./txt/cord-001938-n2d5fw2f.txt
