BREAST CANCER
Since the percentage of losses was significantly differential between groups and especially important in the intervention group (26.1%), it was considered more appropriate not to apply the intention-to-treat principle and a per protocol analysis was carried out [Percentages, means, and standard deviations (SD) were calculated according to the nature of the variables in order to describe the characteristics of each individual in the sample. The assumption of normality was assessed using the Kolmogorov–Smirnov test and, if fulfilled, the corresponding parametric tests were carried out.Chi-squared and McNemar’s tests were used to calculate differences between qualitative variables, percentage of breast cancer risk factors and symptoms identified and adherence to recommendations on diet and physical activity, in post-test between groups and change from pre-test to post-test, respectively.
