  1. CL/C7S the ratio of cervical lordosis to C7 slope; OC2 occiput-C2 lordosis; CSVA cervical sagittal vertical axis
  2. aIncreasing OC2 was associated with lower CL/C7S
  3. bIncreasing CSVA was associated with lower CL/C7S
  4. cPatients with hidden imbalanced sagittal alignment had lower CL/C7S than those with balanced sagittal alignment
  5. dPatients with imbalanced sagittal alignment had higher CL/C7S than those with balanced sagittal alignment
