Classification of patients based on the changes in diaphragmatic thickness during controlled and assisted mechanical ventilation. a Patients were classified into two groups based on the thinning of the diaphragm during controlled ventilation. Patients whose diaphragm thickness decreased by more than 10% are represented by the red line; patients whose diaphragm was unchanged are represented by the blue line. b Patients were classified into two groups based on the thickening of the diaphragm during assisted ventilation. Patients whose diaphragm thickness increased by more than 10% are represented by the orange line; patients whose diaphragm was unchanged are represented by the green line. CMV, controlled mechanical ventilation; AMV assisted mechanical ventilation: Tdi, diaphragm thickness; SE, standard error
