Changes in Pdi_max(cm H₂O) over time in successful weaning and failed weaning patients according to the baseline disease

Group	T₀	T₁
Successful weaning
COPD	50.2 ± 11.9 (4.9)	59.3 ± 13.5 (5.5)^a
Non-COPD	28.83 ± 16.5 (5.2)	33.2 ± 16.9
Failed weaning
COPD	32.1 ± 17.6 (6.2)	32.1 ± 10.6 (3.7)^a
Non-COPD	16.5 ± 13.5^a(5.5)	22 ± 13.5 (5.5)^a

Data are presented as the mean ± standard deviation (standard error). COPD, chronic obstructive pulmonary disease; Pdi_max, maximum transdiaphragmatic pressure.
