Cumulative incidence of liberation from mechanical ventilation by diaphragm or intercostal muscle thickness changes during the first week. Data were compared using Gray’s test with Bonferroni correction for two pairwise comparisons (significant at p < 0.025 vs. unchanged group). Death was treated as a competing risk. The horizontal line represents the time from admission to the intensive care unit (ICU), and the vertical line represents the cumulative incidence of liberation from mechanical ventilation. a Diaphragm: compared with unchanged, those with decreased or increased diaphragm thickness had a lower cumulative incidence of liberation from mechanical ventilation (p < 0.01 in both group). b Intercostal muscle: compared with unchanged, those with decreased diaphragm thickness had a lower cumulative incidence of liberation from mechanical ventilation (p = 0.018). VS, versus. *Significant at < 0.025 vs. unchanged group by Bonferroni correction
