^aGCS, Glasgow Coma Scale; IQR, interquartile range; ICU, intensive care unit; MV, mechanical ventilation; PEG, percutaneous endoscopic gastrostomy tube; ^bof 371 (47.0%) total patients who received MV, data on length of MV were available for 208 patients (56.1%); ^cdaily GCS score data were collected for the first 14 days from the time of subarachnoid hemorrhage. P values are based on the log-rank test. Data regarding time to normal GCS score are presented in Figures S2 and S3 of Additional file 1, along with adjusted hazard ratios.
