Table 2 Meta-analysis of secondary outcomes

From: Proportional assist ventilation versus pressure support ventilation for weaning from mechanical ventilation in adults: a meta-analysis and trial sequential analysis

Comparison Trials (n) Secondary outcomes Summary estimate with 95% CI I2 (%) Cochran’s Q P value
PAV versus PSV for weaning from mechanical ventilation in adults 6 (484) Reintubation RR, 0.49 [0.28; 0.87]* 0 0.81
5 (461) Mortality RR, 0.66 [0.42; 1.06] 0 0.56
5 (276) ICU length of stay (days) MD, − 1.58 [− 2.68; − 0.47]* 0 0.76
3 (122) Duration of weaning (hours) MD, − 0.01 [− 1.30; 1.28] 0 0.57
3 (133) Duration of ventilation (hours) MD, − 40.26 [− 66.67; − 13.84]* 0 0.56
  1. 1. Values of RR less than 1 indicates a reduction in risk for the events with the PAV group
  2. 2. Summary estimate presents the result of fixed-effect meta-analysis
