The relationship between state and trait anxieties. a Linear plot of state and trait scores in normal subjects. A significant positive correlation was observed (ρ = 0.580, p < 0.01). b Comparison of state scores in the high trait anxiety group (HT) and in the low trait anxiety group (LT). State scores were significantly higher in HT than in LT (*p < 0.05). Median state anxiety in HT and LT were indicated with horizontal bars. The vertical bars indicate the range and the horizontal boundaries of the boxes represent the first and third quartiles
