—, indicates non-significant comparisons. Variables not represented (marital status, ethnicity, current employment, age, medical insurance status, number of siblings in the family, Prevent 1, Prevent 2, distress about sibling's cancer, proband gender, proband stage at diagnosis, proband age at diagnosis and time since proband's diagnosis) were not significant predictors for any of the comparisons.
