Table 2 Socio-demographic and medical characteristics of the overall study sample (N = 568) and those of the subsamples of women whose responses to the Breast and Body Image Scale (BBIS) were complete (N = 517) and those whose questionnaires had missing values (N = 51)

  1. MVs: missing values; CES-D: Center for Epidemiologic Depression Scale; QD15: questionnaire filled in 15 days after test result disclosure.
  2. *The body mass index classes “25.5-29.9 Overweight” and “≥30 Obesity” were pooled to obtain more accurate estimates.
  3. a p-value in univariate tests comparing the distributions of the sociodemographic and medical characteristics according to the status MVs / no MVs in the BBIS.
  4. b Adjusted odds ratio of the excess risk of having missing values in the BBIS.
