  • To provide a consolidated measure of error for commonly used landmarks in lateral head films.

Main Methods:

  • Meta-analysis of six relevant studies focusing on cephalometric landmark identification.
  • Integration of findings to measure systematic and random errors.
  • Calculation of standard mean errors and 95% confidence intervals.

Main Results:
