A Kaplan-Meier curve was constructed for the 30-day period, illustrating distinct groups: those without acidosis, those with hyperchloremic acidosis, and those with elevated anion gap. The curve’s values were derived from a Cox regression model. Additionally, a separate Kaplan-Meier curve was generated for various types of metabolic acidosis with an elevated anion gap and mixed disorders, also based on the Cox regression model
