Additional file 2: Figure A1. of Enteral versus parenteral nutrition in critically ill patients: an updated systematic review and meta-analysis of randomized controlled trials

Subgroup analysis comparing the effect of enteral versus parenteral nutrition according to the caloric intake on length of intensive care unit stay (N = 4 studies). Panel A shows the subgroup of aggregated trials in which the caloric intake in the PN group was significantly higher than in the EN group, Panel B shows the subgroup of aggregated trials in which the PN and EN groups received similar caloric intake and Panel C including one trial where caloric intake was not reported. CI confidence interval, EN enteral nutrition, M-H Mantel-Haenszel test, PN parenteral nutrition. Figure A2. Subgroup analysis comparing the effect of enteral versus parenteral nutrition on length of hospital stay according to the caloric intake (N = 7 studies). Panel A shows the subgroup of aggregated trials in which the caloric intake in the PN group was significantly higher than in the EN group, Panel B shows the subgroup of aggregated trials in which the PN and EN groups received similar caloric intake and Panel C including one trial where caloric intake was not reported. CI confidence interval, EN enteral nutrition, IV inverse variance, M-H Mantel-Haenszel test, PN parenteral nutrition. (PDF 148 kb)
