Results are reported for patients according to their diaphragm evolution status at the end of patient follow up. The population was divided in three categories whether the diaphragm thickness presented a 10% decrease, increase or remained stable from baseline to the last assessment. Outcomes are presented after 60 days of follow-up (unless otherwise specified)
