Results The A1A2 measured by CT exhibited an increasing trend from C3 to C7 segments in both groups ( P < 0.001).
Results The A1A2 measured by CT exhibited an increasing trend from C3 to C7 segments in both groups ( P < 0.001).
On the other hand, the transverse diameter of the spinal cord in the C6 to C7 segment exhibited a decreasing trend, which may be due to the smaller transverse diameter of the spinal cord in the C6 to C7 segment compared to the C3 to C5 segment.
