Fig. 2From: Change in diaphragm and intercostal muscle thickness in mechanically ventilated patients: a prospective observational ultrasonography studyThe relationship of changes in muscle thickness between the diaphragm and the intercostal muscles. Among groups stratified according to changes in diaphragm thickness, the percentages of patients with decreased, increased, or unchanged intercostal muscle thickness are shown by a bar graph. Numbers indicate the number of patients in each group. Changes in diaphragm and intercostal muscles thickness were associated with a kappa value 0.28 (95% confidence interval, 0.14–0.41, p < 0.001), suggesting a poor associationBack to article page
