Figure 4 Longitudinal changes in spinal cord cross-sectional area

Mean spinal cord cross-sectional area (square millimeters) by month with SE in controls, patients who recovered, and patients who did not recover. Both patients who recovered and those who did not showed a significantly greater decline of spinal cord area over time compared with controls, which remained significant when models were repeated with data collected after 1 month and adjusted for baseline cord swelling.
