Results from multiple logistic model for the association with positive lymph node status.

<p><i>InSitu</i> were excluded from the analysis. Significant P-values are indicated in bold, nearly significant P-values are indicated in italics.</p

Socio-demographic and medical features of all patients included.

Frequencies of patients by type of stress life events and lymph-node status.

<p>Significant P-values are indicated in bold.</p

Histogram of frequencies (%) of patients with positive lymph node (N1) status by category of life stress events.

<p>Dark bars depict percentage frequencies of N1 patients who experienced repeated stress (at least one event of the category occurred more than once), light bars depict percentage frequencies of N1 patients who did not experience repeated stress (all events in the category occurred once or never). Asterisks indicate significant P-values derived from Chi-squared test.</p

Group 1, at diagnosis.

<p>A) Breslow thickness by UV exposure indicators. B) Breslow thickness by duration of sunny holidays. C) Breslow thickness by gender and sunny holidays.</p
