Effect of stressed assisted ventilation on peak electrical activity of the diaphragm (peak Eadi). SBr stressed (with resistance) spontaneous non-assisted breathing, PSV pressure support ventilation, NAVA neurally adjusted ventilatory assist. The data of all the participants are displayed in the figure. Patients for whom all the conditions were available are represented as white circles. Patients for whom one or more conditions could not be recorded are represented as gray triangles. Only the patients represented as white circles were considered for median calculations and Friedman analysis
