Figure 3. Univariate effects of theophylline treatment on clinically relevant variables of respiratory function.

Figure 3

Box and whisker plots illustrating the full range (boxes) and median values for measures of respiratory function, grouped to test the interaction between SCI level (C1-C5) and theophylline treatment for (A) time to admission after SCI, time to 16 hours of (B) VFB, (C) BMI, (D) first FVC, (E) best FVC and (F) improved FVC. No significant interactions between SCI level and treatment condition were found for any of the measures individually.
