From: IMRT delivers lower radiation doses to dental structures than 3DRT in head and neck cancer patients

  1. Different lower case letters in columns mean statistically significant difference (p < 0.05) (t-test). In columns, compare 3DRT groups themselves and IMRT groups themselves
  2. Different upper case letters in rows mean statistically significant difference (p < 0.05) (One way ANOVA test). In rows, compare mean of the averages themselves and mean of the maximums themselves
