Factors Associated with Postoperative Prolonged Mechanical Ventilation in Pediatric Liver Transplant Recipients

Figure 2

Box plot showing the distribution of postoperative ICU and hospital length of stay stratified according to duration of postoperative ventilation status. Patients in the PMV group had significantly longer ICU and hospital LOS compared with the non-PMV group. ICU: intensive care unit; LOS: length of stay; PMV: prolonged mechanical ventilation. Circles and stars refer to outliers or extreme values.
