Table 3.

Simple linear regression analysis using maximum dose (Dmax) and mean dose (Dmean) in sigmoid colon, anal sphincter and rectum associated with symptom groups. Bold indicates p ≤ 0.05. In the column of Symptom group, the number indicates each symptom group’s averaged factor score (and standard deviation in parenthesis).
