  1. Values are the mean ± standard deviation or number (percentage)
  2. *Differences between groups were evaluated by the two sample t-test or χ2 test
  3. Abbreviation: BMI body mass index
  4. *Note that the minimum sample size for conventional and modified method groups were defined without patients’ information so that an estimated prevalence of 50% for modified method compared to conventional method
