Table 3 Summary estimates of effect for comparisons of ATC vs other techniques on SBT success

From: Trials directly comparing alternative spontaneous breathing trial techniques: a systematic review and meta-analysis

Comparison Trials Risk ratio (95% CI) p value I 2 (%)
ATC/CPAP vs CPAP 3 (n = 247) 1.12 (1.04–1.22) 0.005 0
ATC/CPAP vs PS 3 (n = 276) 1.10 (1.01–1.20) 0.02 0
ATC vs T-piece 2 (n = 157) 1.03 (0.76–1.42) 0.83 81
ATC/PS vs PS 1 (n = 100) 1.04 (0.94–1.15) 0.40 NA
