Computed tomography-derived nasojejunal tube tip-to-gastric antrum path length and short-term outcomes in severe acute pancreatitis

Table 3 Association of computed tomography-derived path length with continuous intensive care unit outcomes

Analysis	Outcome	Variable	Effect estimate	95%CI	P value
Unadjusted Spearman correlation	Total ICU length of stay, day	CT-derived curved path length	ρ = 0.055	-0.216 to 0.317	0.671
Unadjusted Spearman correlation	Post-CT ICU length of stay, day	CT-derived curved path length	ρ = 0.053	-0.218 to 0.315	0.682
Unadjusted Spearman correlation	Mechanical ventilation duration, hour	CT-derived curved path length	ρ = 0.064	-0.399 to 0.509	0.771
Adjusted median regression	Total ICU length of stay, day	CT-derived curved path length, per 5-cm increase	0.192 days	-0.922 to 1.305	0.732
Adjusted median regression	Total ICU length of stay, day	APACHE II, per 1-point increase	0.275 days	0.082 to 0.468	0.006
Adjusted median regression	Post-CT ICU length of stay, day	CT-derived curved path length, per 5-cm increase	0.192 days	-0.914 to 1.298	0.730
Adjusted median regression	Post-CT ICU length of stay, day	APACHE II, per 1-point increase	0.275 days	0.084 to 0.467	0.006

Effect estimates for Spearman-correlation rows are Spearman ρ and are dimensionless; effect estimates for median-regression rows are adjusted median differences in intensive care unit days. Spearman 95% confidence intervals were obtained by 10000 bootstrap resamples. Median regression included computed tomography-derived curved path length and Acute Physiology and Chronic Health Evaluation II. CT: Computed tomography; ICU: Intensive care unit; APACHE II: Acute Physiology and Chronic Health Evaluation II; CI: Confidence interval.
