  1. Abbreviations: ICC: intraclass correlation coefficient; CI: confident interval.
  2. LSN scores of each observer are presented as means ± SD.
  3. *The differences between both observers in LSN scores were assessed by the Wicoxon signed rank test.
  4. †The intra-rater reliability between both observers was assessed by the intraclass correlation (ICC) test.
