Effects on length of stay and mechanical ventilation in studies comparing enteral versus parenteral nutrition. Panel a shows aggregated trials with information on ICU length of stay, Panel b shows aggregated trials with information on hospital length of stay. Panel c shows aggregated trials with information on length of mechanical ventilation (in mean and standard deviation). CI confidence interval, EN enteral nutrition, ICU intensive care unit, IV inverse variance, LOS length of stay, M-H Mantel-Haenszel test, PN parenteral nutrition, SD standard deviation
