Objectives:
The aim of this study was to investigate the association of intestinal permeability with the Nutrition Risk in Critically Ill (NUTRIC) score and the modified NUTRIC score (mNUTRIC) in intensive care unit (ICU) hospitalized patients.
Methods:
One hundred and fifty ICU hospitalized adult patients admitted between October 2017 and April 2018 who stayed for >24 h in the general ICU were enrolled in the study. Nutrition status was estimated using the NUTRIC score, an ICU-specific nutrition risk assessment tool. The NUTRIC score was calculated using the exact same thresholds and point system as developed previously. Admission plasma endotoxin and zonulin concentrations were measured to assess intestinal permeability.
Results:
Median plasma endotoxin and zonulin increased with increasing mNUTRIC and NUTRIC categories in the overall study population and in the glutamine-deficient subgroup. Multivariate binary logistic regression analyses showed a significant association between the plasma endotoxin (odds ratio [OR], 2.04; 95% confidence interval [CI], 1.8-3.52) and zonulin (OR, 1.11; 95% CI, 1.03-1.20) levels with NUTRIC category in the overall population and the glutamine-deficient subgroup. Similar results were obtained when using mNUTRIC.
Conclusions:
Results from the present study provided evidence that higher plasma endotoxin and zonulin levels are associated with a progressively higher NUTRIC score in critically ill patients.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
