a
Scores in the INFO25 module scales and items range from 0 to 100. Higher scores mean a higher level of information received, higher information wishes, and higher satisfaction.
b
Descriptive statistics from Arraras et al [11, Table 2], assessment during treatment (n = 451).
c
Independent samples t-tests; significant p-values are shown in bold for ease of viewing.
d
Items 50, 51, and 53 have a dichotomous answer (yes/no).
*
Comparisons that remain statistically significant at a level of 0.05 after Bonferroni correction (the p-values reported are not corrected for multiple comparisons).
