ABG improvement
Fifteen studies exhibited ABG improvement with a total number of
interventions (n=1135). Based on
the pooled analysis (Figure 3A), ET showed a non-significant difference
in mean ABGs improvement compared to MT (SMD: 0.03; 95% CI -0.33 to
0.39; p = 0.87). However, highly significant heterogeneity
(I2 = 89%, p < 0.00001) and publication
bias were found (Figure 3B).
