Secrecy correlated negatively with age (Figure 2A; r = -0.322; P < 0.05) and the level of education correlated positively with Secrecy (Figure 2B; τ = 0.314; P < 0.01), i.e., the older patients were less willing to display secrecy, but, interestingly, for better educated ones covering up their health problems seemed preferable.
