Nonlinear association between estimated plasma volume status and acute kidney injury in acute pancreatitis patients

Figure 1 Flowchart of the screening and enrollment of study participants. AKI: Acute kidney injury.

Figure 2 The nonlinear association between estimated plasma volume status and acute kidney injury in patients with acute pancreatitis. A: Duarte formula-based estimated plasma volume status; B: Kaplan-Hakim formula-based estimated plasma volume status. Adjusted for all covariates as model 3. Solid lines indicate the odds ratio of acute kidney injury and dotted lines represent the corresponding 95% confidence interval. Odds ratio = 1 was set as the reference line (takes the upper limit of 99.9%). D-ePVS: Duarte formula-based estimated plasma volume status; KH-ePVS: Kaplan-Hakim formula-based estimated plasma volume status; AKI: Acute kidney injury.

Figure 3 The relationship between estimated plasma volume status and acute kidney injury according to basic features. Except for the stratification component itself, each stratification factor was adjusted for all covariates as model 3. D-ePVS: Duarte formula-based estimated plasma volume status; KH-ePVS: Kaplan-Hakim formula-based estimated plasma volume status; OR: Odds ratio; CI: Confidence interval; AP: Acute pancreatitis; SOFA: Sequential organ failure assessment.
