Ventilator settings and respiratory parameters at baseline (pre-randomization) according groups. Data presented as mean ± standard deviation. Pairwise comparisons between groups by Tukey Honest Significant Difference Test where p = 0.05 was taken as a threshold for these post-hoc comparisons: * Difference (p < 0.05) between Not ready for weaning group vs. SNR group. † Difference (p < 0.05) between ZERO CPAP tolerance failure group vs. SNR group. § Difference (p < 0.05) between SBT failure group vs. SNR group. SNR: screened and non-randomized, FiO2: fraction of inspired oxygen, CPAP: continuous positive airway pressure, PEEP: positive end-expiratory pressure, SBT: spontaneous breathing trial
