  1. FNA fine needle aspiration, FNB fine needle biopsy, CS conventional smear, LBP liquid-based preparation
  2. aOnly neoplastic cases are included
  3. bThe 25-gauge FNB group showed a better diagnostic yield in terms of specific tumor discrimination compared with the 22-gauge FNA group (P = 0.018)
