Weight gain at different time points during the ventilation protocol. Results are presented as means ± standard deviation; n = 7, 6 and 5 animals for HiP-C, HiP-Met and LoP groups, respectively. *P < 0.05 for HiP-C group vs. all other groups; ** P < 0.01 for HiP-C group vs. all other groups; *** P < 0.05 for HiP-C group vs. HiP-Met and P < 0.001 for HiP-C group vs. LoP groups. LoP-C: low pressure-no metformin; LoP-Met: low pressure-metformin; HiP-C: high pressure-no metformin; HiP-Met: high pressure-metformin.
