Density plots for: (a) knowledge score in 115 Italian physicians participating in the survey; (b) risk perception score (RPS). Both GKS (D’Agostino–Pearson’s normality test K2 = 5.747; p-value = 0.057) and RPS (K2 = 5.453; p value = 0.066) were somehow skewed and did not pass the normality check. Dotted line represents median value (46.67% and 32.0%, respectively).
