The left column lists the demographic variables. The 2nd–4th columns show average values of the variables across the group, with their standard deviations in brackets. Education level was rated according to a six-point scale defined by Verhage, which ranges from primary school (1) to university level (6). Nonparametric tests were used to test the group difference for PANSS (permutation test) and gender (Chi-square)
