Figure 3

Kaplan-Meier curves of the probability of remaining under mechanical ventilation after the onset of weaning. (a) Duration of mechanical ventilation (log rank test, P = 0.075). (b) Days off mechanical ventilation (log rank test, P = 0.003). (c) Weaning period (short-term): no need for mechanical ventilation for the next 48 hours (log rank test, P = 0.003). (d) Weaning period (long-term): no need for mechanical ventilation until ICU discharge (log rank test, P = 0.003) for patients in the electrical muscle stimulation (EMS) group as compared with those in the control group.
