With a female predominance of 63.16% (48\/76) and a high proportion of thymoma-associated MG (TMG) of 63.16% (48\/76), the overall in-hospital mortality was 2.63% (2\/76) and the average duration for mechanical ventilation (MV) use was 17.09\u2009\u00b1\u200913.36\u2009days (0\u201353\u2009days). In contrast to the patients with anti-acetylcholine receptor (AChR) antibodies, muscle-specific tyrosine kinase (MuSK)-associated MC exhibited a shorter MV support (5.20\u2009\u00b1\u20095.07 versus 17.40\u2009\u00b1\u200913.24\u2009days, p\u2009=\u20090.023), length of intensive care units (ICU) stay (6.00\u2009\u00b1\u20094.64 versus 19.16\u2009\u00b1\u200917.54\u2009days, p\u2009=\u20090.046), and hospital stay (16.00\u2009\u00b1\u20094.12 versus 34.43\u2009\u00b1\u200920.48\u2009days, p\u2009=\u20090.011).
