Figure 2 Residual plot (A–D): The X-axis represents the independent variable, while the Y-axis represents the residuals. On the Y-axis, values are coded as 0 (indicating survival or correct diagnosis of septic shock) and 1 (indicating death or diagnostic error). (A) Residual plot of in-hospital mortality versus prehospital lactate level in sepsis patients. (B) Residual plot of in-hospital mortality versus prehospital ETCO2 in sepsis patients. (C) Residual plot of septic shock diagnosis versus prehospital lactate level. (D) Residual plot of septic shock diagnosis versus prehospital ETCO2.
