1
Information on both social and relationship status was derived from the questionnaires and is therefore only available for “participants”;
2
Information on tumor thickness and Clark level was obtained from physicians when patients gave their written consent to contact them and is therefore not available for “non-eligible” and “non-respondent” patients.
